The pattern for the Sew Together bag is by Sew Demented, and is available for purchase on Craftsy. If you do want to make a bag like this, I highly recommend the tutorial by Quilt Barn on her blog. There are many extra little steps not mentioned in the pattern, but the tutorial explains them all.
I chose some lovely Tula Pink fabrics for this bag, and mixed them with some other pinks from my stash.
I've got a second bag cut out already, and it will be all Kaffe Fassett fabrics. I'll tackle it another day. My first bag took me about 10 hours, but I did hand sew my bindings down. I'm hoping that the second one will be slightly quicker.
I didn't think I really needed one of these bags, but now I'm on holiday in Auckland I'm finding it really useful for storing my hand quilting supplies.
