Congratulations! I had an old treadle machine, with the puzzle box of attachments, when my children were babies, and I was, well, very poor. I made all the curtains for my children's rooms on it, complete with ruffles for the girls. I was able to put the prettiest hem on miles and miles of ruffles in no time at all, because one of the little attachments was a cool hemming foot. My girls were the envy of their friends for those pretty curtains.
I may have to look for another one of those. I sold it when I could afford a better machine, I have now a Pfaff that I bought back in the early 80's. You know, because of those ruffles, I got to where I could so really fast on that treadle machine, and the only thing I missed having was the zigzag.
The other cool thing about it was that the bobbins held more thread, so I didn't have to rewind the bobbin so much.
