Bring modern geometric style into your home with the Prism Cushion Cover, featuring rows of upright and inverted triangles made with plain and variegated yarns. My reason for choosing the name is that each triangle of variegated yarn looks like light that has been split into a spectrum of colours, adding beauty to the design.

The Prism Cushion Cover is made to fit a 43 cm x 43 cm cushion inner and the pattern can be altered to increase or decrease the size. It’s a fun-to-make, repeat pattern that’s easy and quick to do.

Included for your convenience, with the pattern PDF, is a Row Counter Worksheet PDF specific to the pattern. There is also a PDF containing Helpful Tips for beginners.
