I never thought of combining sequins with tatting until Marti on the Ice Drop Addicts Facebook page showed some absolutely gorgeous pieces. Marti's are stunning! Mine are just fun. ;-)
Now that I've found a way of adding sequins that I like, I will probably incorporate more of them into Ice Drops.
Another tatter (I'm sorry, but I can't remember who) said that she used beads to help hold the sequins in place.
No pictures were posted, but this is what I tried, and I think it worked pretty well!
