I am working on one right now that is 47 x 59 and another that is 80 x 100. I work on one for a bit then change over to the other. That combined with making placemats for Jim for Christmas, sort of stretches things out a bit. I do work on the smaller one a bit more, because it is for a brother-in-law and want to get it done. (even though I have plenty of time. It is for Halloween). On top of that, I am not very fast at all. I try to concentrate on making the stitches even. (a tough thing for me).
So to answer your question, actually I cannot say. :D
