Well... I finally worked myself up to finished the sewing on the units for clue 3... I still need to cut them apart and press them and pray to the quilting gods that the size works out... I'm going to say that I have a few 2" HST that are actually about 1 7/8"... but I'm going to say close enough... I can get that much wiggle here and there.
Back to the table to cut and press... wish me luck and encouragement... this has been a struggle to be motivated to complete this week...
