I love looking at how shapes fit together and have wanted to create a tessellating circle design for some time. Circular motifs can be tricky to fit together and it is common to find the circular shape becomes slightly distorted when motifs are pieced together, so rather than create motifs that are square or octagonal, I have designed cross-shaped infill pieces that protect the shape of the large circles.
When making the small infill circles you are asked to make a magic loop to start. You can find a technique download that explains how to do this by following this link. Instructions on how to add surface crochet can be found by following this link.
The pattern includes a clear layout plan and a chart is also included for reference when joining the small circles.
