I've made a series of small crafts in walnut shells and want to turn them into lockets of a sort by gluing a ribbon (or thin strip of cotton fabric) to the outside so I can tie them shut. I'm having trouble getting the glue to work properly, especially with ribbon.
I've tried Mod Podge, which didn't hold at all, and LePage wood glue, which mostly works if I use thin cotton fabric but is flimsy enough that it comes off with a bit of a yank. It's even worse if I try to use a silky ribbon or a piece of lace. Are there better ways to get fabric and walnut shells to bind, or should I just be very careful with them as is? (I know the other option is to attach the ribbon on the inside, but that won't let me secure it closed.)
