Timing on this is funny. We needed a few pieces of fabric for some projects and stopped in at one of our LQS. She had a customer who bought the Tilt'albe and loved it, but as has already been mentioned the price was a little steep. Her husband took a look at it and made several out of wood, then brought them to the LQS to see if she would offer them for sale.
They are one piece (no detachable legs), but the way he made them there is a high side and a low side. You can turn it over to make the angle steeper or flatter depending on what you need. She was selling them for $20, so I snatched one up and brought it home to give it a try. I like it on the steep side, and it looks nice too.
If you know someone who works with wood, the design is very simple; it is just shaped like a "Z" with one of the legs a little longer than the other. Hopefully the pics give you the right idea.
