Another Sudoku Quilt
I love patchwork but I am as slow as the proverbial snail and my sewing is as crooked as the trail the snail leaves. I was stunned when our great friend Glenda made 2 Sudoku quilts for the girls. Simply amazing - a gift of friendship that required an enormous effort, lots of time and considerable expense. THANKYOU!.
