Mom's Butterfly Doily

I made this for my Mom. It took me about 6 months to do. But in the meantime I received 2nd degree burns on my right arm. I spilt boiling water down my arm. I kept the arm proped up on a pillow and kept right on tatting. They said because I kept using my fingers and wrist it saved me from going thru phyical therapy. It stays on Mom's dining room table.
