It's done just the same way as the other block is done, just different widths of the fabrics and both sides of the tubes are strips, rather than the one large purple one in this case.

I love this block, it is a great way to use up scrap strips. Who doesn't have 2½" strips laying around. It only take 4.

Ok--thanks--your quilt is so pretty.

Go ahead and mix it up and have some fun with it. It is a very bright, pretty colored block. Can't wait to see it finished.

And thank you!!!!!! :)

Really pretty colors very happy! Block looks great i would stay with GD's request.

do you have colored pencils or crayons? draw the blocks on a piece of paper and play with the color layouts.

I love that block and really like colors!

No matter what you do it will turn out wonderful!

I can't wait to see more!! :D:D
Love it.
