What is a tube quilt, please?

I found these addicting! I tried a block and then couldn't stop! I have a ziplock bag full of tube blocks all blue and white that I hope to put together into a top someday! They are ridiculously easy and fun!

Very pretty!!! Is there a tute on here for making the tube blocks?

Thank you so much for the info. The tut makes it so easy for a tube quilt. You can see I am just a beginner.

Okay, how do you do a tube quilt?? I love your color selection!

Please a "how to do" tut.
