My friend would like for me to loom knit a baby sling for her 3 week old. I am a little unsure of how to do this. My idea was to possibly create the sling on the largest Boyle Rond Loom (like a deep pink,I cant remember but i think it is a 40 peg loom). I was thinking of knitting about 8-10 inches on 20 pegs then increasing to the full 40 pegs for where the baby will be cradled for another 20-30 inches (depending on the length of the child) and then decreasing to 20 pegs for an additional 8 inches. I was then going to knit the ends together to form a loop. This will be my first time attempting a project without a set pattern. Ideas? Thoughts? Help?
