If you’ve ever looked at a beautiful fabric design and thought, “I love it... but which base should I choose?” — you are definitely not alone.
One of the questions I hear most often is:
“What’s the difference between your Cotton WPC and Poly WPC?"
And honestly, it's a great question — because the fabric base you choose can totally make or break your project.
Why Fabric Base Matters
When you're sewing, especially if you're working on bags, accessories, or anything with structure, the fabric base you pick is just as important as the design. A base that’s too floppy might not hold shape. One that’s too thick could be frustrating to sew on your machine. And sometimes, even the feel of the fabric can change how happy you are with the final result.
So how do you know what base is right for you?
It depends on a few key things:
-
What you’re making (e.g., a slouchy bag vs. a structured pouch)
-
What kind of sewing machine you’re using (some machines struggle with thicker bases)
-
Your sewing comfort level and preference
-
How much drape, structure, or waterproofing you need
That’s why I created a simple, clear cheat sheet to help break it all down. Fabric Base Cheat Sheet PDF
The Bases We Offer
All of the bases listed in the cheat sheet are available as digitally printed fabrics in our shop. Here’s a quick overview to get you started:
Cotton Woven

Easy to sew on any machine.
-
Not waterproof, but great for flexible, everyday projects.
Cotton Canvas
-
Much more structured than woven.
-
Holds shape well, ideal for bags that need strength and durability.
-
Still cotton, so it’s easy to sew and press.
Poly WPC (Waterproof Canvas)
-
Made from polyester, so it has a smooth, slightly drapey feel.
-
Waterproof and vibrant in color.
-
Easier to clean and flexible enough for pouches, organizers, or totes.
Cotton WPC (Waterproof Canvas)
-
Also waterproof, but has a firmer feel compared to Poly WPC.

Has more of a matte, natural cotton finish.
Smooth Vinyl

Shiny, flexible, and durable.

Some domestic machines may need a teflon foot or vinyl needle to glide through smoothly.
Glow Vinyl

Perfect for fun accents, Halloween projects, or adding personality to your make.
And for each one, we’ve included details like GSM (weight), drape, waterproof properties, best uses, and purchasing options — so you can choose the best match for your project with confidence.
