Quilting is a lot faster on Tabblo than in real life I suspect.

Make one square that you like (in this case a 15 point origami star).  Make many smaller copies of it. Upload to Tabblo. Arrange to suit.

Zip. Boom. Squish.  Tabblo Quilt.

Now...if I could only find a way to print this out on a queen-sized blank quilt and have robots stitch the grid between the quilt pieces and maybe even on the star legs themselves....

hmmm...  ;-)
