I used the heart shape off of mine by tracing it with tracing paper, then using that with sewing type tracing paper and a wheel to mark the shape on my fabric. I did this about twenty years ago, but I know they still sell sewing tracing paper, but you buy the tracing wheel separately. After doing all my quilts the first thirty years on a June Taylor cutting mat, then broke down and bought a self healing mat on Amazon (it was labeled as an architect’s cutting mat since they are the same and much less money). Major difference. My rotary cutter slid a bit on the June Taylor, but with the self-healing mat, my cutting is so much more accurate.
