Observations about Interlocking Rings

The tail of the first ring can be hidden by tatting over it with the first few double stitches.

 

Leaving a loop of thread sticking out gives me something to hold onto while putting the narrow Celtic shuttle down through the ring and down through the ring again.

Then I turn the ring over (back side) to get the first half of the first double stitch snugged up tightly against the previous ring, making the sticking out loop disappear.

Tat the ring and close, turning the tatting to front side. Continue the same steps for subsequent rings until the final ring.

To tat the final ring, go down through the previous ring, down through the first ring, and down through the previous ring again.  Tat the ring and close. 

I find that moving and turning the other rings out of the way helps with closing the final ring tightly.

I did not invent the technique of tatting Interlocking Rings with a Celtic shuttle, these are just some things that help me remember how to do it, so sharing in case it helps you too.
