If that doesn't work out,....you're going to have to substitute. Either the same brand, but a different color choice, or a different brand altogether. And that is probably going to require some digging. Remember, you want to try and stay in the same fiber content/weight/gauge family if you can. For bernat, this means 70% acrylic, 30% soft cotton blend/worsted (medium) weight/18 st to 4 inch gauge.
Use the
yarndex as a starting point; with that you can find at least some brands of yarn that fit the same gauge as the bernat. good luck!
