I will also opt to double up in the 2 month group. Why not?
Also, I don't mind a short cut of fabric. Mine are all going to be a tad smaller, widthwise. I used a fat 1/4 bundle, so one F4 of each was all I had. Once I trimmed off the selvedge and then cut them in half, they were a tad short. Can't help that, sorry.
