I made mine with 3 levels: (a square within a diamond within a square) I used 5 colors of 7 oz skeins. Now the outermost color used almost all of 1 7 oz skein, and the rest in decreasing amounts. The skeins I used are 365 yds long. The innermost color used hardly a third of that amount, so plan your skeins accordingly.I

Now, speaking of sizes… the finished size of mine using heavy worsted weight yarn and an I hook is about 36-38” square. Two such squares together would make a complete twin bed cover. That being said, the size can be anything you desire, from a small hook, 2 layer square that is tiled to make a larger piece, to a larger hook and bulky yarn or rug yarn to make a floor throw. Try it a couple of ways and you may just end up with your own creation!
