That is awesome!! I always believe that it's not necessarily the machine that makes beautiful quilts........it's the hands who operate the machines.
I don't own a fancy machine. I have only 2 machines, both bought for less than $200 (one was from Costco, the other from WalMart). I have put together some eight queen-size quilts on both of them; and nobody would've known that I didn't use a fancy-schmancy machine on any of them.
I envy that you have your older machines. I wish I had my grandmother's machine. She had sewn on a treadle.
