These 3" long aluminum repair hooks are a must-have for your notions pouch! The hook on one end is used for picking up dropped stitches, and then you can slide the tool through the picked up stitch and knit off the tapered end like a normal knitting needle if needed. These tools work on yarns as small as lace and as large as worsted. Please note: this listing is for a single hook, and we get random assortments of colors sent to us (that may be the only blue we've ever received, and we've seen purple and green from time to time as well), so your color will be chosen at random. You can put a note in the box below for a prefered color, a color you absolutely don't want, or just a warm or cool color preference, and we will do our very best to accommodate!
