I made several models using fabrics with the same dimensions but different techniques. Since I had more ideas than metal zippers, I ended up using other small zippers I had, and even one with a snap button.
To determine the fabric size, I used the following rule:
Width = zipper width + 2 × seam allowance
Length = 2 × zipper width + 2 × seam allowance
Most zippers measured 12 cm, so I used fabric pieces 14 cm wide and 26 cm long. Width = 12 + 2 × 1 = 14 Length = 2 × 12 + 2 × 1 = 26
I made nine pouches with 12 cm zippers, one with a 13 cm zipper, one with a 15 cm zipper, and one with a snap button.
The assembly principle was the same, with small variations depending on the model. I started by sewing the zipper, joining the outer and lining fabrics and topstitching the zipper, then made adjustments according to each model.
Round pouches with enclosed seams – A and I
· A – This was the first one I made, and I had difficulty because the zipper was very thick and had already been cut, which made it hard to sew the edges neatly. Also, since I used three layers of fabric (four in some places), the fold for the French seam was too wide and bulky, making it hard to sew.
· I – For the blue one, I used thin denim and a metal zipper (from jeans), which helped reduce the thickness of the edges and made the pouch larger.
Flat pouches – B, F, and K
· B – A simple pouch with lining. The only difference is that instead of using the outer fabric as a single piece, I cut it in half because it resembled an envelope.
· F – To align the stripes, I had to unpick one, mark the position, and sew it back. When folding, I shifted the zipper about 2 cm downward and enclosed the seams with French seams.
· K – This one has no lining; I finished it with an overlock stitch. I should have changed the bobbin thread to match the zipper color for a better look. It's larger than the others because the zipper was longer.
Cube-shaped pouches – C and H
· C – When sewing the second side of the zipper, I left an opening to turn the pouch inside out after finishing, so all seams are enclosed.
· H – I cut the corners and used French seams on them to enclose the seams.
Vertical pouches – E, J, and L
· E – When folding, I shifted the zipper about 2 cm downward and made a fold at the bottom so it could stand upright. I finished the interior with bias tape.
· J – This mini backpack is the only one without a zipper. I had no more 12 cm zippers, so to use the already cut fabric, I made this one. The construction method is not very different from the others.
· L – This one has a 15 cm zipper, so it's larger than the others. I used upholstery fabric and decorated it with an applique like the ones I did on the kimono. I made square corners so it could stand vertically.
Expandable pouches – D and G
· D – I made this one by accident while trying to make G and made a mistake, but I liked the result. When closed, the expandable part can face up or down—it's practically a 3-in-1.
· G – This one is expandable with the opening on the side. I finished the interior with bias tape.
