I'm late finishing this week's challenge and then I noticed that I used Chainging instead of Punzel. Well I will post it anyway and give Punzel a try later.
I made this challenge for my DH who turns 65 on November 1. I thought this tangle was perfect to create numbers with.
It's not finished yet. I think the numbers will show up more if I color it. Will do that later.
Here is the tutorial for both Chainging and Punzel.
