This beautiful Luminous quilt is made using 2 1/4" strips (not just any strips).
The Ombre Strips.
This gives the quilt that wonderful illuminating effect.
This pattern also uses The 60° Triangle Tool.
A paper template is included with the pattern, but you might just want to get the tool for yourself.
There is also a paper template for the triangle shapes you will need to complete the quilt.
You might want to use a 60° Triangle such as the one shown below by Quilt in a Day.
The triangle needs to have a blunt top and measure at least 7 1/2" tall.
Finished size of quilt is 48" x 56"
