I've been staring at this on the floor of my sewing studio for three weeks:
Last night I got home from work and after dinner I decided enough was enough. I cut the pieces crosswise into 18" lengths, then paired them up, and sewed them together. Then I rearranged them and sewed those together.
And this is also a reminder that the Scrap Slab Triangle Quilts tutorial is live and for sale in my Etsy shop here.
