UPDATE: See my video about using the oval wheel at this post.
The oval Spirograph gear produces a sort-of heart shape when you use the holes near the pointy end.
It produces 8 points or petals with the 144/96 ring, and 7 with the 150/105 ring.
Since Valentine’s Day is just around the corner, I thought I’d play with it a bit. I used the 144/96 ring and combined the oval with wheels 84 and 60, which also give 8 points.
If you have a kid in grade school, you could quickly produce enough valentines for the whole class! Try some fancy paper or cardstock and add sparkles or other embellishments.
