I have played with Inkscape and find it is easier than Illustrator in some respects. (definitely cheaper! at free)
Here is a quick diagram of the weave I used for the necklace in my previous post.
The beading pattern is two 11°, one accent bead. For the portion with the Swarovski 5301’s, the Swarovski is where the step-up is made. This reinforces the crystal. I use nymo D doubled, a personal preference.
Any questions, I’ll be more than happy to answer!
