It would take me about 10 hours to make something like that. Did you find it too, too hard? Did you use quilt batting?
I estimate it took me about 8 hours and I wouldn't say it was hard, just different than anything I have done. Now that I have done one, the second would go much faster and I would pick my material better. The animal print was great to work with and stuck well but, for some unknown reason, the green didn't want to stick and I ended up fussing with it lots.
There is quilt batting under each green section and was supposed to be on the top of the lid (so it could be a pin cushion) but I skipped that part.
