To make the 4 block mini quilt, students need:
1 yard background fabric
1/3 yard for block centers
1/3 yard for long triangles
1/3 yard for inner/outer twists (first color)
1/3 yard for inner/outer twists (second color)
I recommend contrasting fabrics in either color or value for the inner/outer twists.
Also, large scale prints are not suitable for this pattern.
