What to do? I thought of a few solutions:
- go to the store to see if I could find more (that would mean leaving the house)
- try to find a close enough match (it is a pretty neutral background after all but I didn't have anything in my stash)
- sew together the pieces I had left to make do
I decided to sew together the strips before cutting them so that some of the sashings have a seam or two in them. I have no problem with this solution and it is probably what granny would have done.
