Here's the first placemat under construction.
Since I took this photo, I've sewn the rows together on this one and pieced another one as well.
I did have to cut out a few more squares as I wanted each placemat to be made of 48 different squares but I used my Go! cutter so cutting out about 50 squares took very little time at all. I have the remaining 4 placemats all pinned and ready to sew so the sewing, quilting and binding of them all should keep me out of mischief over the next few days. :o)
