Wow. Really neat fix! And your cat could easily be the sister to my male cat Coconut Cream Pie. Same tuxedo style cat with the little white mittens and back feet. My kitties scratch on an old crate that holds my canned goods. I don't care that they are destroying it. I think it adds character to that specific furnishing.
I agree with your idea about blank notecards. I feel that if they are handmade, they should have a handmade sentiment inside as well. Yours look beautiful! I don't think they look simple. I think combined they are compex. Wonderful share!
Very cute! I once made a set of these, nesting inside one another in three sizes for my sister who was travelling a lot. She loved them. The smallest bag she used for her jewelry, the largest one for bras, and the middle size for pantyhose. They helped keep her luggage and motel room sorted. And you are right. It is a very neat pattern, and really not that hard of geometry to figure out. Great job!
