For a simpler printout, go to my post about intricate snowflakes.
I've spent the day designing snowflakes for a papercraft project that I have in mind. These circles were a great starting point. I printed off the template at a very low density, and then drew my snowflake designs with darker lines over the top. Eventually I will trace these lines with a thin sharpie, and erase the lines I don't want. If you don't want to deal with the extra lines, just place this print out under the paper on a light box or window. I'm sure there's a much easier way to do this on the computer. I'm certainly open to ideas, but for now, this has worked really well for me. I could spend hours making up new intricate patterns! For inspiration, I've been looking at photographs of real snowflakes! For a simpler print out and ideas, see my earlier post about drawing intricate snowflakes.
This lesson goes very well with one of my favorite seasonal crafts. Snowflake ornaments!
