Trinity, Stripology Mixer Pattern by Gudrun Erla, the popular designer behind GE Designs. Trinity is a striking design with its triangular blocks made from 10 in. squares and 2-1/2 strip precut fabrics -- or dive into your fat quarter stash. Construction is very easy with the Stripology XL ruler from Creative Grids and designed by GE Designs, and GEasy point trimmers. Instructions for using regular rulers are included. The pattern comes with six different size options: crib, lap, twin, full, queen.
