Two of the patterns are included in the instructions with the set.

For the third, I took out my felt pens and drew on the outside of the ring, then added an inside pattern to match. Added some music, and here you go.

Parts of the video are speeded up.

How many points will you get? It depends on the same mathematical formula that determines the number of points of a hypotrochoid. You don’t have to do the math, though. Just use this Table of Spirograph Points in the reference section of this website.

Once you’ve drawn your epitrochoid, try drawing a design inside the ring to match it before you take the ring off the paper, as I did in the video.

Here’s another idea: use it as a picture frame or greeting card with a photo or message on the inside!

You can also draw an epitrochoid around another wheel, rather than a ring. Try it.

Drawing around a Spirograph rack, or around open shapes made with Super Spirograph parts, also creates epitrochoids, but that’s a subject for another video.
