We found an error on the Caroline Bag pattern Under material requirements for the small bag, you need 72 triangles, not 38.
In the directions to make the small bag sides, you are making two sides. You need 72 triangles. Make 4 sets of 18 triangles each (two per side)
An added note: Unfortunately, Creative Grids discontinued that wonderful ruler that allowed us to cut multiple perfect 60 degree triangles.
