I have the Martelli but ever since I tried to change the blade I can't get the thing back together again GRRR!!!!! I had long since thrown the wrapper in came in out by the time I changed the blade. I'm going to the Fort Worth quilt show tomorrow and if they are selling them there maybe I can get them to show me how to get it back together. I usually don't have a problem putting stuff back together, must have a trick to it or something or......ok, maybe it's me!
