I love knitting in the round
but could not find a way to knit a decent sock on the looms available at local craft stores. Usually the smallest one available to make baby hats or bulky mittens just wouldn't do what I wanted. So then I found the Letter D. It seemed to be perfect for what I had in mind. The best part of round looms is that you can put it down and pick it up any time, and you can do this craft even if you never knitted before. Its easier to regulate the tension on the loom than it is on straight or double point needles when your a beginner. No counting stitches as you cast on. (Unless you want to) Both having their advantages in that traditional knitting can be faster for experienced knitters with other pattern options such as fancier stitch patterns, but you can do some things such as a simple cable, or special wraps on the round knitter.
This is mainly about crafting already available materials into a handy knitter. Your only limited by your imagination, truly fits this situation. I added an additional feature making the peg (nails in this case) removable so you can add or subtract pegs as needed.
I will add more content as I try various things with my knitter.
