I need a bunch of muslins sewed together

My son has made a strange request for his birthday and I am hoping to find someone with good sewing skills to help. It will probably be a pretty easy one! He loves the muslins that we used when he was a baby and he wants to take 20 of them and sew them into a blanket.

These are the muslins that I am talking about: https://www.amazon.co.uk/gp/product/B00EXVJH4M/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
