DIY cloth wipes - Advice please

Hello ladies,

I will be cloth diapering and using cloth wipes. I want to make my own wipes out of single layer flannel. What would be a good size? I have enough fabric to make:

- 64 pieces of 4.5" x 4.5"

- 56 pieces of 5.5" x 4.5"

- 49 pieces of 5.5" x 5.5"

- 42 pieces of 6.5" x 5.5"

- 36 pieces of 6.5" x 6.5"

I will be doing laundry every other day. What is a good count to have and good dimensions to work with? If need be, I can get more fabric if the finished sizes I listed are too small.
