I have made several of these biscuit blankets and given them for gifts along with a pretty square plate to go under the blanket. The design is so pretty and looks difficult, but isn't. Momwolf is right, you have to move the yarn to the back in order to K1; just remember to bring it back to the front before you sl 5. Enjoy the pattern!!
