When I use 2 colors in crochet I use yarn containers. Got them in store at Joanne's with 50% coupons so not that expensive. Lid screws off and there is a hole in the top for the yarn end. Could probably make something also. Comes in large and a small size and I love mine and have several of them for projects. Mary

Mary, I saw those yarn container sold on eBay. They look like tea/water containers but without the spout. I saw them sold at Walmart. Last week, I went to Walmart and they were on clearance for $2.50 each. The containers were made of plastic.

Nancy, I purchased a device a few months ago from Wendie's Crafts on ebay. Mine holds two skeins of yarn and they unwind from the outside as you crochet. I just checked by typing in "yarn unwinder" and the first item brought up was the one I bought. It sells for $18 for the double one. The skeins are loaded onto two dowels and the frame is made out of plastic pipe (lightweight). Hope this helps.
