Do you crochet granny squares? Using the free online drawing tool, Grid Designer, you can use images of your granny squares to create a palette of squares. Then use that palette to lay the granny squares out in any pattern you choose to create your design.
See the video on adding images to a palette for an example with quilt squares... you can do the same with images of your granny squares. https://youtu.be/iMeelJwnqq0
