How to turn a pillow case into a bag?
I have this pillow case I decorated and I want to turn it into a bag. Any ideas?
If you cut it and sew a bit, it would make a really cute hobo bag!
Cut off the edges so it’s rounded and then sew them back together. Then you can take the ends and tie them together for the straps.
Look up “Make a hobo bag from a pillowcase” on Google, you’re bound to find some good pics.
