Thanks Jaba and Brat for more dimensions. I am pretty close to 20 1/2", 20 3/4" actually, but I can deal with that. I just thought maybe I was off because I can't see how 20" is going to work with a 6" block. But hey, I can also deal with a little mystery and will anxiously wait for Feb. to see how it all comes together. LOL.
I am a little "off" but not so much in my sewing. LOL Another grey, foggy day in the pacific northwest. But compared to the drought, fire, record snow and wind in the rest of the country, I'm not complaining. Brat, fishing!!. Must have warmed up a little in Wyoming. But then, you guys are TOUGH.
