I purchased this loom to knit a blanket using Bernat Blanket Yarn #6 super bulky. This loom is not spaced wide enough to accommodate this size yarn. The knitting is too tight and the yarn can barely fit through the spacing. However, it is a great high quality Cindwood loom. I should be able to use it with #4 and #5 yarn with ease. Just beware - if you're purchasing this queen size loom to use with bulky yarn you may run into some challenges.
