is there anyway to loom knit and have those gaps closed or tighter?
There are several things you can do to eliminate the gaps. If you are using the Knifty Knitter type looms that have the wide spaced apart pegs, you can use a thicker gauge yarn or double up on the thinner yarn. This will make the stitches tighter, but the resulting fabric will also be thicker. Alternatively, you can get looms that have pegs that are closer together. Authentic Knitting Board sells looms like this, as well as CinDWood, and you can get the Martha Stewart Weave and Loom kit that you can use both larger, wider spaced pegs and smaller, closer pegs depending on how you set it up. Hope this helped!
