It took me ages to finish these ... some more baby wraps for Nicholas. I like wraps nice and big, so I take a piece of fabric 110cm x 110cm and then trim off the selvedge and square it up. I tend to use a rotary cutter, easier to get nice and crisp lines.
I bought the fabric from Spotlight years ago and put it aside for a present or special occasion. I used Birch poly cotton bias to go around the edges.
