Forgot to update the pics of the Tiffany class works mentioned in the original post, so here they are:
Tiffany flower - with tin plating.
Tiffany heart - before soldering with tin.
Now the reason I dug up this old thread wasn't because of the pictures above but for using this same thread for other handicrafts...
Made a hat for myself using so called Trinity Stitch or Raspberry Stitch. Was a first try since I haven't knitted all that much and never a pattern stitch other than colored knitting. Feeling very pleased
It feels nice on head too and the folded ribbing will keep ears warm.
Here's colored knitting socks for my mom. Designed the flower pattern myself but am not 100% happy with it. It's supposed to be (Finnish White) Rosa spinosissima "Plena".
