I have a 14" lap top frame made by a local fellow. I saw Harry Barnett's "sit on conversion kit". I got it and it went on my frame in 5 minutes. The best part is how it works. I have a queen size in it. The "sit on" attachment has a spinner that allows me to turn the quilt 360 degrees as I work on a block (only 128 out of 140 to go). I love it. Now to deal with the sore finger. Aunt Becky and I haven't been able to development a positive relationship yet. Gary
