Sharon b ~ yes, it does us a special ruler.
I used 'Lil Twister' ruler, and 5" blocks (aka Charms) to make the table toppers.
If using 10" blocks (aka Layer Cake), uses the 'Twister' ruler.
PROCESS~
Put together 'charms' [I did 4x5]
Add a border [In 'Picnic' the yellow/check is the original border]
Then using Lil Twister ruler start cutting apart [it will be on the bias]
Sew back together [you end up with twisted pinwheels]
Add a border [or two, or three]
FINISHED
I want to play with this some more.... but I have some other projects that HAVE to get done :(
IT does go fast!!
