I acquired two of these wood art cases this weekend and am converting one of them into a sewing kit. I removed the inserts and the hardware so the trays are simply stacking inside. I painted the inside edges of the trays and then added cardstock on the bottom of the two trays and the bottom and lid of the case. It will now open like a suitcase instead of like a book.
I used black foam core to create dividers and the support for the trays in the bottom of the case.
I added some Altoid tins with labels on them for storing needles, measuring tape, etc. I added a magnet to the bottom of the silver tin (Making Memories embellishments) and added straight pins. There is little chance of having pins all over even if you accidentally knock it over. There is room for scissors, marking pencils, thread, etc.
I have added a few supplies from my stash - thread, pins, measuring tape, etc.
The trays simply stack over the supports in the bottom and the lid keeps everything in place once it is closed. I will be adding a cool little fabric name tag as well.
