All HSTs are sewn together and one 72" x 72" quilt top is complete. Happy, happy me.
I've splurged and ordered extra wide backing fabric. Something to do with not wanting to make a whole bunch more HSTs for the back if I had to piece something into a normal width fabric that would make it wide enough and still cohesive with the front design. I went with the cost versus sanity line of thinking, and decided as my sanity was already hanging by a thread I had best just order the extra wide.
So, as soon as that fabric has arrived basting and quilting will commence. Meanwhile I have hexies to keep me entertained.
