Mod Triangles is a fast and fun project that can be made with charm squares or strips.  It is one simple block.  Make a lap (47" x 57")  or a queen (86" x 92").  For the lap version you need 40---5" charms and 2 5/8 yds of background and binding fabric.   In place of the charms you can use (5) 4" x 45" strips of 5 different fabrics.  The queen version uses (91) 5" charms or (12) 4" x 45" strips of fabric and 7 1/4 yds of background and binding.  The project pack includes the pattern and a pack of 3.5" THANGLES.
