So, if I cut these into 2 1/2 inch squares then I need to cut the muslin into 4 1/2 inch squares. I think that's right.
And if I used 3 inch squares I would need to cut the muslin into 5 inch squares? Just wondering because I just found a bunch of 6 inch squares in the bottom of a drawer that I haven't seen in a very long time. Can't even remember why I have them. I think they're leftovers from projects that I squared up for later. And now is later (LOL). They're all very light so maybe I'll use a leafy green for the big squares in this one. I have a pretty mottled green with a small, scrolly leaf pattern.
