More Variations On A Theme

I was curious to see if I could apply the half-zipper technique to my standard zippered bag construction – that meant figuring out a way to have the seams concealed between outer layer and lining. Turns out to be quite easy.

Instead of cutting two sides 6″ x 8″ I cut one piece 6″ x 16″ – I sewed the zipper to one long edge, added lining. Here’s the crucial difference – I didn’t top stitch the zipper, instead I steam pressed the zipper making sure both lining and outside were well pressed away from zipper edge. That allowed me to add the slide, fold the bag in half, separate the lining from the outside, sew the remaining side seam (from lining to outside with little tab inserted near the zipper) making sure zipper protruded on the lining side as I sewed. Next I made sure to open the zipper. Finally, I stitched the outside bottom, turned bag right side out pulling lining beyond the zipper, folded lining bottom seam allowance under and top stitched the lining bottom, pushed lining back inside bag, pressed.

I had a zippered bag with a “loop” zipper, and concealed seams.

I made six from four fat quarters which I had just bought so now I know exactly what my materials cost:

The fabric to make six 6″ x 8″ bags cost me $12; batting – I used large pieces leftover from a quilt (batting costs $26/m so say I used 1/16 m ) – $1.65, thread (can’t calculate), zipper (I buy zipper tape and slides from The Zipper Lady @ $36 for six yards (that includes exchange as well as shipping and handling), $10 for 40 slides (25¢/slide) – I get two bags from 1/2 yard so zipper costs me  $10.50/six bags (a bit less than if I’d bought zippers individually at the fabric store). Total for the materials: $25.65 for six bags = $4.27/bag. Labour: It took me 2 hr to make six bags – time per bag, ~20 min (that’s pressing the fabric, cutting fabric and zippers, sewing it all together, pressing again). At $20/h labour works out to $6.65/bag. Total costs: $4.27 + $6.65 = $10.92. Profit – 20% of costs = $2.19. Total cost of one 6″ x 8″ bag: $13.12!

People tell me I should sell them at the craft market – I’d be selling the bags at a loss if I charged $10/bag!

So even a small zippered bag is a gift of love.

That’s it for bag-making for now!
