I agree with Ingrid. I don't even know if the stitch I used for seaming HAS a name!
But it all disappears into a solid fabric when you felt. Especially seaming up the inside sole, that won't show at all.
Well, I've completed the uppers and inner soles for both of DH's clogs, so now I just have to make the two outer soles and seam everything together. Goal is to finish by next weekend so I can get going on Christmas gifts for the family.
