Our Vinyl Ribbing is fully round solid vinyl ribbing. It comes in two sizes small and large. Size small can be wrapped on a size 16 hook or smaller depending on the style and brand hook you are using. The large size can be tied on hook size 8 or larger, depending on the style hook it can be tied on size 10 hooks too. This vinyl ribbing is very easy to work with and can be used for numerous patterns. If you take and pull the vinyl ribbing in your hands before tying it you can make the diameter of the ribbing smaller. This allows you to be able to tie it on smaller size hooks. It’s a must have for your fly tying table. Comes in 2 yard bags.
