this is a quick project I did trying to get SVGs from programs running on my Manjaro Linux machine, (I believe Inkscape in available on Windows but I'm unsure about Kritta, but there are plenty of other drawing options) 
I first used Kritta and the multi brush and mirror options to draw the snowflakes in symmetrical forms I then saved as PNG files and opened them in Inkscape I did a trace bitmap action with "single scan" and "centerline tracing (autotrace)" selected, I also went into the "fill and stroke options" and selected "hairline" under the "width" setting to create a single fine line for XCS to cut (with other settings XCS wanted to do double cuts on the outline) 
I then applied those settings,(sometimes it seemed that I needed to reapply the "hairline" width setting after finalizing the bitmap trace, perhaps it doesn't need done at the start, at least the one that I tried that way came out alright..) deleted the bitmap from the Inkscape workspace scaled the snowflake to 2 inches and saved the centerline trace of the snowflake as an SVG file.
I loaded those SVG files onto a USB stick and put them into my windows machine that runs my XCS software. loaded the files double checked my size, set my cut settings and cut them out, I still need to work on refining my cut settings a little and I am waiting on my honeycomb cut bed in the mail so my cuts are a little more smoke stained on the front and back then I would like but this is only my second little cut project and I am satisfied with my early results =) 
I hope you enjoy cutting out these little snowflake ornaments as much as I have enjoyed the process of making the files! =)

side note the second snowflake had some sloppy line drawing done and may have issues if cut out at too large of scale, but I'm not worried about fixing it (because it's not that nice of a snowflake anyway) as I am accepting it as a learning mistake ;)
