Puzzles that have been put together and sealed make great wall hangings. I have made several, some tiny other huge.
The bear one I made for my oldest daughter that collects bears.
These kitty ones I have for sale.
I am currently working on a large one, but not doing well. It is mostly shade of white and shades of blue. I think it will take me forever to get it put together. It is of a couple of children angels and will be lovely when finished and framed. My dear husband makes the wood frames around each finished puzzle. I will put photos here of the few I have done.
