This is the niftiest stitch holder I've seen. It opens from either end, so it doesn't matter which direction you use to put the stitches on, or put them back on the needle. Plastic so they're lightweight and won't stretch your stitches, and they come in 3 sizes to match your gauge. Large is 6 1/2" long for needles size 5 through 11. Two in a package.
I love these stitch holders because you can transfer stitches from either end or easily knit off of them.
