A vector or raster graphic program for Tatting lace?

Muskaan answered a question in the last post, she used templates, sometimes used Robin's free template, I guess the polar guide with 12 divisions for snowflakes.

That made me go to Robin's blog, tutorial page. 

Keeping on

Graph with TatHelper

Checking old tatting books in the Antique Pattern Library web site, looking for inspiration for my graphic challenge, found one that it's not very known, Mrs Warren Needlework designs from 1869.

Graphing so far

Tatting has 2 basic knots that create a stitch, 2 basic shapes built of those knots and that's all you need to develop really complex designs. You can also change one of those shapes with its original counterpart, the bare thread.  

Corina MeyFeldt's Snowflake in TatHelper

Corina Meyfeldt is a tatter from Rumania. Blog: http://cmhandmade.blogspot.com.ar/ On her blog Corina posted this snowflake pattern which uses bugle beads. Beaded tatting is fun and colorful but using bugle beads does require some planning ahead.
