***DESIGNER UPDATE***
I am managing to finish the mystery. Tiffani and her girlfriend are out doing some running around, errons that she needed to do while she was here, so I am back at the cutting mat and sewing machine and pressing on (pun intended!) till she gets back home.
I just cut the borders and find that I do have extra fabric. Fabric A will also be the binding, but I have 7/8 of a yard left, plenty for binding. Fabric B had 1/4 yard left and fabric C had 3/4 of a yard left. Hope that helps on your fabric planing if you haven't already cut, if you have.. Stash time
Off to sew the borders, write the instructions and then computer goes off for the rest of the night
