These are a few of the scarves and beanies that I made.  I even bought a loom set for flowers.  It's easy and fun to use.
  I used the biggest round loom to make adult beanies.  As for the length of the scarf, it  varies depending on the person who is using it.  I also made infinity scarves.  Thank God for the invention of the  knitting looms!!!  A real dodo like me can knit!!  LOL
