Extra Large Flour Sack Towels, Jumbo Blank Tea Towels 33"x38", 100% Cotton, Set of 7
The Size Bakers Reach For — And the Towel That Does the Rest, Too
At 33×38 inches, this is the largest flour sack towel in Mary's lineup — and it's no accident that 33×38 is also the standard size stocked by baker supply brands. When you need to cover a proofing bowl, drape a risen loaf, or handle a job the 27×27 is simply too small for, this is the towel.
Same 130 thread count diagonal weave. Same 4-side hem and corner loop. Same pre-washed, lint-free cotton. Just more of it — built for serious kitchen work, large-format embroidery and printing, and anyone who's ever thought their regular dish towel wasn't quite big enough.

What You Get
The Full Size Lineup — Choose by Task
All sizes share the same 130 TC cotton, 4-side hem, and hanging loop. The difference is coverage.
More Surface Area. More Possibilities.
The extra 6–11 inches over a standard flour sack towel makes a real difference for tasks where coverage matters.
Why 33×38 Is the Standard Baker Supply Size
When bakers go looking for a proofing cloth, they don't search for any flour sack towel — they look for the 33×38. It's the size baker supply brands have standardized around, because it's large enough to cover a full proofing bowl, drape over a banneton, or wrap a loaf for the second rise without the towel pulling tight or leaving the dough exposed.
The 130 thread count diagonal weave is breathable enough to let fermentation gases escape, dense enough to trap moisture, and smooth enough to release dough without sticking when properly floured. Pre-washed and pre-shrunk — so the size you see is the size that shows up.

For Embroiderers & Printers: A Bigger Canvas
The 33×38 opens up design possibilities that the 27×27 simply doesn't have room for — full-width recipes, edge-to-edge scenes, oversized script lettering, or multi-element layouts. The 130 thread count diagonal weave is stable, hoops flat, and takes ink and thread cleanly across the full surface.
Easy to Wash, Built to Last
Pre-washed and pre-shrunk. Gets more absorbent with every wash as the cotton fibers open up. Simple care keeps these working for years.
Common Questions
What size flour sack towel is best for bread proofing?
33×38 is the size baker supply brands use as their standard, and for good reason — it's large enough to fully cover a proofing bowl, drape over a banneton, or wrap a large loaf without pulling tight or exposing the dough. The 27×27 works for smaller batches, but for anything full-sized or larger, the 33×38 gives you the coverage you need. See our full guide to bread proofing with flour sack towels for more detail on technique.
How is a flour sack towel different from cheesecloth for straining?
Flour sack towels are woven much more densely than cheesecloth — they're durable enough to strain, twist, and wash repeatedly without falling apart or leaving fibers in your food. The 130 thread count cotton is also lint-free, which cheesecloth is not. For tasks like straining yogurt, ricotta, or kefir, flour sack towels are often preferred by home cheesemakers precisely because they hold together and can be washed clean for reuse indefinitely. The 33×38 size gives you more surface area to work with when gathering and twisting than the 27×27.
Are these pre-washed? Do they need to be washed before the first use?
Yes — every towel is pre-washed and pre-shrunk before it ships. You can use them straight out of the bag. For baking use specifically, the pre-washing removes any finishing agents that might transfer to dough, so these are food-safe right away. They become more absorbent with each subsequent wash as the cotton fibers open up further.
Why buy the 33×38 instead of the 27×27?
The 33×38 is the right choice when you need more coverage than a standard 27×27 can provide. The main cases: covering a large proofing bowl or banneton during bread making, handling jumbo kitchen tasks, straining larger batches, or printing/embroidering designs that need more canvas than 27 inches wide. If you use your towels mostly for everyday drying, wiping, and smaller craft work, the 27×27 is the better value. Both share the same 130 TC cotton and construction quality.
Can I use these for large-format embroidery or screen printing?
Yes — the 33×38 is popular with embroidery studios and screen printers who want a larger canvas for full-width designs, oversized lettering, or edge-to-edge patterns. The 130 thread count diagonal weave is stable and holds thread and ink cleanly across the full surface. Pre-washed and pre-shrunk, so your design won't shift after the first wash.
