Do you need to catch floats?
So for knitted fabric that’s likely to come into things that may catch on floats, like fingers and toes, we must trap or catch long floats to anchor them to the fabric.
How many stitches can you float?
Floats are not usually caught because their colors runs are never more than 5 to 7 stitches. Many knitters prefer to catch their floats to maintain a tidier wrong side and to keep the floats from becoming troublesome later or catching on your fingers or rings when you pull on your sweater.
