Colorful Optical Illusion

Snowflake Puzzles, 350 pieces. What it says on the tin! The changing thickness of the curving lines provided a good guide to assembly. These are reliably good hand-cut puzzles (available on Etsy) with thinner wood and no whimsies except for the signature piece. You can see the shiny finish obscuring some of the image because of my inept photography.  4/5
