If you've been tossing out the plastic zip bags that comforters and linens come in, this tutorial will change that habit. I take those bags — the kind most of us either shove in a drawer or throw away — and turn them into small, see-through pouches you can actually use: for storing journals, holding little packets of paper scraps or fabric bits, protecting a journal in transit, or keeping a current project together so everything stays in one place. And the whole thing is genuinely quick to make.
What we cover
This tutorial walks through cutting and sewing a storage pouch from upcycled plastic packaging, then finishing it with inked paper circles, brads, and bakers twine. I show the process on a small size so you can scale up or down to whatever you need.
What you'll learn
How to prepare plastic packaging for sewing — large, stiff comforter bags can be relaxed with a quick pass of a heat gun so they lie flat without losing their appealing crinkled texture. I cut along the seams to open the bag out flat, then cut to the size I want.
How to cut and square up your pouch pieces — I fold the plastic in half and trim all four sides so everything is straight before I start sewing. You don't have to do it this way — you can sew first and trim after — but if you like things to sit neatly, squaring up first makes the whole process easier.
How to sew the base seam and then the sides in one go, including:
- Sewing the bottom edge first as a single straight line, backstitching at start and end
- Folding the bottom seam down so it sits flush inside the pouch
- Tapering the side flaps slightly for a cleaner finish
- Sewing up one side, across the top of the fold, and down the other side in a single continuous pass so you end up with a proper pocket
How to tie off the thread so the seam holds — I backstitch at both ends and then tie a knot by hand as well, because I'd rather overdo it than have a seam come apart later. That "raggedy" little knot at the corner also adds to the handmade look.
How to make and attach the brad closure, including:
- Punching or cutting two large circles and two small circles (circle punches work, or cut by hand — imperfect circles are genuinely charming)
- Inking the edges of the small circles so they stand out against the plastic
- Attaching one brad through the large and small circles together, then through the front of the pouch at the top, and bending the prongs flat inside
- Attaching a second brad through the front flap only so the pouch can be looped shut
How to finish with bakers twine — I tie a knot directly onto one of the brads, wrap the twine around to close the pouch, and trim to length. Black and white twine shows up beautifully against the plastic, though any twine or thin string works.
How to vary the size and use — the same method scales from a tiny embellishment pouch up to something large enough to store a full journal. I made several sizes in one session without measuring anything; it's all approximate and visual.
Tips & gotchas
If your plastic is very stiff and crinkled from being folded in the packaging, a brief pass with a heat gun will relax it enough to lie flat and sew cleanly. Brief is the key word here — you're warming it, not melting it. Keep the heat gun moving and stop as soon as the stiffness releases.
You don't need to pin or clip the layers together before sewing, but a clip or two does help keep the sides from shifting, especially on a wider pouch. On my first ones I didn't bother and they turned out fine, so think of clipping as optional rather than essential.
When you trim the side flaps after folding, taper them just slightly — a small diagonal cut at the corners makes the pouch look much neater when it's finished. Again, I don't measure; I just eyeball it and trim a little at a time.
If your circle punch isn't cutting cleanly through the plastic or paper, just cut the circles by hand with scissors. Some of mine are hand-cut and they honestly look better for it — the slight imperfection feels right on a handmade object.
Backstitch at the beginning and end of every seam, and then tie an additional knot in the thread tail. The plastic doesn't grip thread the way fabric does, so that extra security matters.
When you attach the brad that goes through both the large and small circles and then through the pouch, put your hand inside the pouch before you push the brad through so you don't accidentally pierce both layers. Only the front layer should get the brad.
The see-through quality is genuinely useful: you can store ten different in-progress journal projects, one per pouch, and see exactly what's inside each one without opening it. I've used them for fabric scraps, paper collections, and even finished journals going out to customers. The fabric scrap version in particular turned out to be my favourite — there's something about the texture of fabric seen through the crinkled plastic that makes it look like a little treasure.
