I brought the box to show my mom and told her owning craft supplies is a separate hobby from using them as I kind of just like knowing I now have a “stash”. But with it so far I have made new kitchen curtains, backed a quilt with it, lined a couple of tote bags, and have plans for using the fish-themed prints at DD’s house
