Nice video to follow...going to go find a slightly used tank top now!

Cool, a very Green idea. I will have to give this a try when the dog needs food again.

I have a favorite pattern for a shopping bag = where size is easily adjusted. The only thing I did change up was to pad the handles with batting to make it easier/ softer to grip. My friend had depended upon large brown papers bags with handles in order to carry groceries from car to home. The store stopped carrying bags with handles. The shopping bag I designed and made is large enough for the clerk to insert a paper bag first and then load the groceries.

"30 Minute Shopping Bag" bag pattern designed by Geta Grama is the best $10. investment I've ever made for any pattern. Here's the link: https://www.getasquiltingstudio.com/...ng-bag-pattern

I only use the ones I make. I use home dec fabric. I check the red tag tables at JoAnns or wait for a sale or use coupons. I have a Simplicity bag pattern or use an old McCalls craft book. There are tons of patterns on line. I also make my own produce bags. The most expensive part of the project is the webbing for the handles. I bought a huge wheel of it on line so that helps or sometimes I just use leftover fabric strips. Good luck and and Yay town for going plastic free!

how clever! i may try this after finding the right tank top

I,too make my own bags, there's plenty of free patterns in allfreesewing.com. I use home decorator fabrics ,and some pillowcases I no longer use. I double the fabric(just line it with same fabric ) for my bags that will hold heavier items,like canned goods,

what a neat idea, never thought of reusing the birdseed bags.Thanks for the tip.

Don't make the bags too large or some bag boys think they must be filled to the top and you won't be able to lift them. Ask me how I know.

Here's a nice video that shows how to include snaps on your bag to keep it in a compact folded shape when it's not holding stuff: https://www.youtube.com/watch?v=gtIc6dK2OwE

Home decorator COTTONS are washable. I use synthetic web straps (like you find on backpacks), and always include a pocket for small stuff like mints or gum. Decorator samples often are close to 15"x18", and I use those as-is.
Serge top of pocket and hem; attach to side of bag before assembly.
Seam and serge sides and bottom before hemming top edge.
Fold each bottom corner, matching side seam to bottom seam, and stitch across a triangle to make flat bottom on bag.
After hemming top, attach ends of 18" straps halfway between center and side seams. I seal ends with a candle flame to prevent fraying, then stitch around a square with zigzag stitches.
Do not exceed the weight of 1 gallon of milk and they'll last for years.
