I just viewed the video on tube quilting and want to give you instructions on how to do it. The originial idea came from Cozy Quilt Designs and a girl from Missouri Star Quilt Co. gave the demo in case you want to check out their websites. This technique has the look of a string block or an hourglass block when finished so keep this in mind. Try different layouts when finished. You'll be surprised.
1) Cut two strips 2-1/2" wide of contrasting fabs (dk. & med.) a yd long or to suit
2) Sew tog
3) Press to dk side
4) Measure. Your new width shd now be 4-1/4" wide
5) Cut (1) 4-1/4" wide lite colored fabric to coordinate w/the other 2
6) Now lay them on top of ea other
7) Now make a tube by sewing them tog down one side; then change directions (to keep fabric from bowing) and sew tog back in other direction
8) With your ruler lay the 45 degree line on your qtr. inch seam and cut
9) Slide the ruler down to the opposite seam and line up again the 45 degree line with the seam and cut
10) Repeat steps 8 and 9 until you run out of fabric to cut (no chance!)
11) Have fun playing w/your blocks!
The demo made 2-1/2 blocks out of 3 strips of fabric!
Hope this is helpful. You can read the other posts about the pt. issue some are having. Align everything properly so you will have good points on your blocks. Accuracy is key with this technique. Have fun. :-)
