I found a tutorial on youtube somewhere, but I can't find it again.
Sew your strip together like this.
jelly roll-solid-jelly roll
You need the same amount of each pairing - so divvy your fabric up in little stacks that look nice together.
Go ahead and do that for each tube strip. It goes fast when you get the hang of it. Don't worry.
Now, try out some layouts.
sew your blocks together.
OK, let me know if you have any questions. I know this was a pretty slap shot tutorial, but maybe the pictures explain my technique better than my words.
Have a great day!
