I went onto websites and checked out books from the library and spent lots of time and money in the yarn sections of various crafty stores. I've done other little crochet projects, but I was particularly proud of these:
They're blocked with a lot of pins and a mixture of glue and water. Details are in the pattern I got from a blog whose owner is quite the snowflake-maker. This is the same pattern, but two different sizes using different hooks. I sent the smaller one to my dad for Father's Day (it fit in the card better) because he's just as meticulous and detailed as a snowflake... get it?
So I now have one snowflake for my future tree. At this rate, that tree should be fully covered by the time I'm a grandmother and can pass them on to someone who just has to be related to me to get them. Gotta love heirlooms.
