To the Point #141, Paper Pattern
This pattern uses fun and simple piecing methods to make these triangles without templates. It comes with 3 sizes, and is layer cake, fat quarter, or scraps friendly. I recommend this pattern for advanced beginners. I also recommend starching fabrics before cutting (I like the Best Press starch) to prevent stretching during sewing and cutting.
See the 2nd photo for sizes and material requirements. The crib size does not have borders.
