This week I have been having a blast tatting snowflakes with NiteLite and NiteLite ExtraGlow glow-in-the-dark thread. This is 40 and 30 wt polyester thread. The NiteLite glows the best, but is finer than a size 100 cordonnet thread. The ExtraGlow is thicker and is about the size of 100. It tats up nicely and is SO MUCH FUN to look at in the dark! Below are 2 pictures (larger than actual size) with Rozella Linden's snowflake 2006 pattern. The flake on the left is NiteLite ExtraGlow (about 1.75" across) and the one of the right is NiteLite (about 1.50" across).
