I have all from 2/0 to a 10. Skip tooth, reverse tooth etc. I mostly use a 1,2 and 3. If I'm cutting 3/4" wood I get to a 5,6 or 7. Depends on the wood.
I finally finished this one tonight. The picture was from Karen's Whimsey web site. Hope you like it. I'm not sure what I'm going to do with it though, probably hang it on the garage wall with the rest.
