Your design is ready and have a deadline. Now you need the right shirt to put it under that design.
Most guides start with a brand name. We start somewhere else: the decoration method. In 48 years running a Milton, WA production floor, we’ve watched the blank shirt decide half the final result before a single stitch or drop of ink touches it.
The wrong fabric weight cracks screen print ink within a year. The wrong construction twists your logo off-center after five washes. The wrong cotton spin turns a clean DTG print into a fuzzy one.
This guide is the exact framework our team uses every day at Northwest Custom Apparel. Finish it, and you’ll know which blank fits embroidery, DTG, DTF, or screen printing, plus the specific models we pull off our shelves for Washington crews, offices, schools, and events.

The best place to start isn’t a brand name. It’s a framework.
The 4-Step Blank Selection Framework
Four decisions determine whether your blank works. Skip one, and the shirt fights your print instead of showing it off.
- Step 1: Match your blank to your decoration method. Every method needs a different fabric surface. Screen printing needs a stable, flat surface. DTG needs a smooth, tight knit. Embroidery needs density under the needle so stitches don’t sag.
- Step 2: Match your fit to your audience. Construction crews want a boxy, durable cut. Corporate teams want a retail fit with a softer hand. Schools need youth sizes alongside adult ones.
- Step 3: Match your weight to your use case. Daily workwear needs heavyweight cotton. A one-time event runs fine on mid-weight. Premium retail merch leans lightweight and soft.
- Step 4: Match your construction to your timeline. Side-seamed shirts hold their shape wash after wash. Tubular shirts are cheaper and faster to produce, but they twist over time.
For the material science behind cotton, polyester, and blends, see our fabric selection guide.
Step 1 starts with the number printers care about most: fabric weight.
Understanding Fabric Weight: GSM and Ounces Explained
Fabric weight is measured two ways: GSM (grams per square meter) or ounces per square yard. Multiply ounces by 33.9 to get GSM.
| Weight Class | GSM / Ounces | Best For |
|---|---|---|
| Lightweight | 130-150 GSM (4.0-4.5 oz) | DTG, water-based screen print, summer events |
| Mid-weight | 150-180 GSM (4.5-5.5 oz) | The all-around workhorse, most methods |
| Heavyweight | 180-220 GSM (5.5-6.5 oz) | Plastisol screen print, embroidery, workwear |
| Super heavyweight | 220+ GSM (6.5+ oz) | Streetwear and statement pieces, test for shrinkage |
A Bella Canvas 3001 sits around 145 GSM, right in lightweight territory. A Gildan Softstyle G640 sits at roughly 153 GSM, the mid-weight standard. A Gildan Heavy Cotton G500 sits around 180 GSM, our default recommendation for construction crews who wash their shirts after every shift.
Weight tells you how heavy a shirt feels. The spinning process tells you how smooth it feels and how clean your logo prints.
Ring-Spun vs. Open-End Cotton: What the Spinning Process Means for Your Print
Open-end (rotor) cotton gets spun by blowing fibers into a rotor where they twist together fast. Production runs cheap and quick, but the surface comes out coarser, with loose fibers that soak up ink unevenly. It works fine for budget giveaways and one-time events.
Ring-spun cotton gets combed, drawn, and twisted continuously through a ring spindle. The yarn ends up longer and stronger, and prints come out sharper and more consistent. The shirt feels softer from the first wear.
Combed ring-spun cotton adds an extra combing step that removes short fibers before spinning. This is the premium standard, and the smoothest surface for DTG printing and fine detail on screen print. Bella+Canvas Airlume is a branded version of this process.
Compact spinning takes ring-spun a step further, using suction to condense fibers before twisting. It’s the softest, strongest option, with the least pilling over time.
For a full comparison of how cotton performs against polyester, see our cotton vs. polyester guide.
How a shirt gets sewn matters as much as how the yarn gets spun.
Side-Seamed vs. Tubular T-Shirts: The Detail That Determines Fit
Tubular construction knits the body as one continuous tube with no side seams. It’s cheaper to produce, but a tube doesn’t match the human body. After a handful of washes, the fabric twists, the side seam drifts toward the front, and your logo goes off-center.
Side-seamed construction cuts separate front and back panels and sews them together at the sides. The shirt follows the body’s natural shape and holds that shape through repeated washing. Your logo stays where you printed it.
Rule of thumb: if the shirt gets worn more than five times, choose side-seamed. We’ve seen construction crews bring back tubular shirts after ten washes with the logo rotated 30 degrees off-axis. Side-seamed shirts don’t do that.
Now that you understand weight, spin, and construction, the last variable is fiber content, since not every blank is 100% cotton.
Cotton vs. Blends vs. Performance: Quick Fabric Selection by Method
100% cotton absorbs every ink type evenly with no dye migration risk, though it shrinks 3-5% unless pre-shrunk. It remains the universal standard for screen printing and DTG.
Cotton-poly blends (50/50 or CVC) add polyester for durability and reduced shrinkage. CVC, short for Chief Value Cotton, prints almost like 100% cotton because of its high cotton content. Standard 50/50 blends need low-bleed plastisol on dark colors to prevent dye migration.
Tri-blends (cotton/poly/rayon) feel exceptionally soft with a drapey hand. The rayon content requires lower curing temperatures, since standard heat can scorch the fabric. These fit retail brands and boutique merch best.
Performance polyester wicks moisture but demands specialty inks and lower heat. DTG doesn’t work well on it. This is the right call for gyms, sports teams, and outdoor events in Washington’s wet climate.
For the deeper material science behind each fiber type, see our fabric type guide.
With fabric type covered, here’s how each decoration method actually performs against the blanks above.
Decoration Method Compatibility Matrix
| Decoration Method | Ideal Fabric | Ideal Weight | Best Blank Examples | Why It Works |
|---|---|---|---|---|
| Screen Printing (Plastisol) | 100% cotton or CVC | 180-220 GSM | Gildan G500, Port & Company PC54 | Stable surface holds ink; heavyweight resists puckering on multi-color runs |
| Screen Printing (Water-Based/Discharge) | 100% ring-spun cotton | 145-180 GSM | Bella Canvas 3001, Gildan G640 | Smooth surface lets ink absorb and soften into the fabric |
| DTG Printing | 100% combed ring-spun cotton | 145-180 GSM | Bella Canvas 3001, Next Level 3600 | Tight, smooth knit resists fibrillation; cotton-rich surface holds pre-treatment |
| DTF Printing | 100% cotton or high-cotton blend | 145-200 GSM | Bella Canvas 3001, Gildan G640, 3001CVC | Hot-melt adhesive bonds best to cotton fibers; works across weights |
| Embroidery | Dense, high yarn-count fabric | 180 GSM+ | Gildan G500, Carhartt work shirts, polo pique | Dense fabric anchors stitches without puckering; thin fabric sags under the needle |
| Laser Engraving | Leatherette, structured materials | N/A | Richardson 112 caps, leatherette patches | Requires specific substrates, not standard t-shirt fabric |

Here are the questions we hear most often from customers picking a blank.
Frequently Asked Questions About Choosing Blanks
Heavyweight 100% cotton or CVC, around 180-220 GSM, works best for plastisol screen printing. The Gildan G500 is our default recommendation. The extra weight resists puckering during multi-color runs and holds up under an industrial press. For water-based or discharge ink, drop down to a lighter, ring-spun option like the Bella Canvas 3001.
A 100% combed ring-spun cotton tee in the 145-180 GSM range prints cleanest with DTG. The tight, smooth knit prevents fibrillation and holds pre-treatment evenly, giving you sharp detail on photo-realistic designs. The Bella Canvas 3001 and Next Level 3600 are our top picks.
Ring-spun cotton produces a smoother, stronger yarn than open-end cotton, resulting in sharper prints and a softer feel. Open-end (rotor) cotton spins faster and cheaper, but the surface comes out coarser with loose fibers. Ring-spun costs a bit more and delivers a noticeably better result on both embroidery and print.
GSM stands for grams per square meter, the standard unit for measuring fabric weight. Multiply ounces per square yard by 33.9 to convert to GSM. Lighter shirts (130-150 GSM) suit soft, drapey wear, while heavier shirts (180-220 GSM) suit workwear and embroidery.
Choose side-seamed construction for any shirt worn more than five times. Side seams follow the body’s natural shape and hold up through repeated washing. Tubular shirts cost less to produce but twist out of shape over time, dragging your logo off-center.
Yes, untreated 100% cotton shrinks 3-5% after the first few washes. Look for “pre-shrunk” or “sanforized” on the label to minimize this. Cotton-poly blends shrink less because the polyester content resists moisture-driven fiber contraction.
Dense, high yarn-count fabric at 180 GSM or heavier holds embroidery stitches without puckering. The Gildan G500 and polo pique fabrics both anchor stitches well. Thin, lightweight tees sag under the needle and distort the finished logo. See our custom embroidery services for the full process.
Yes, heavyweight 100% cotton blanks like the Gildan G500 work well for both methods. The dense fabric that resists puckering under a needle also holds plastisol ink evenly across a large screen print run. If your order needs both methods on the same style, this is the safer starting point.
Not necessarily. A very expensive organic bamboo shirt might feel amazing but could be too delicate for heavy screen printing. We match the price to the application. For a one-day event, a mid-range cotton tee is often the most logical and cost-effective choice.
This usually happens on low-quality polyester blends where the shirt dye “bleeds” into the ink. Selecting a high-quality 100% cotton blank or a premium blend with dye-blocking properties prevents this issue and keeps your colors bright.
