I actually bought one of the patterns a few weeks ago...then I "killed" my sewing machine. Think I jammed the gears somehow. The only thing I see as a "problem" with the pattern, one of the beds that you can make they tell you to attach a piece of gosgrain(sp) ribbon to it for the cat to play with. That is the type of ribbon that Zingo ate about 2 years ago and would not give back! Took the vet 5 days and many unpleasant medicines and things to get Zingo to give the ribbon up. Then the vet stuck it in a baggie and tried to give it back to me...strange man...anyway since the ribbon on the pattern seems to be more for show than anything else I am going to try one without it. Hopefully I can get the machine fixed soon adn I'll let you know what happens.
