All the instructions you will find are not the tube system, but it's the easiest in my opinion. There is a book published by the Piecemakers in California that is really easy to understand and it a good source for your first bargello. I believe those instructions are long strips rather than the tube system, but at any rate you do a lot of sewing/unsewing to get the pattern to move in the right direction. I am beginning a wave bargello this weekend, using 24 fabrics and I can't wait!
