Wow!! Very Impressive!! I too have been trying to figure out a way to make one and have a few ideas, but this is by far the very best one. I love that it is lightweight and portable, important criteria for me too. I'd be interested in knowing the total cost. It looks like the pvc pipe is fittings, correct? At Ikea a couple weeks ago, I found a 1" thick plank of table top wood in the discount room for 9.99. I just had to get it. It was 24 x 70 and hubby cut it down to 60", then today I bought foldup banquet table legs at Harbor Freight for 17.99. All I need now is the extension for the machine so I have level surface for quilting.
