I just created a new circle/cog design to complement the string pieced circles in a baby quilt. Would you like to see how to draft these quilting designs using Art and Stitch? There is a free video tutorial on my blog post this week. Along with free pdfs of the quilting designs. This one would be very doable (even without a computerized machine).
