Hi @sobeamber! Welcome to the Glowforge 
I recently answered another member’s message, so I’ll copy and paste that content here, hopefully it will start you out!
- I use my Samsung Tab4 tablet to draw puzzles and puzzles shapes with the tablet pen (chosen specifically for drawing puzzle shapes!)
- I use the Concepts app ($10 ish to export as SVG) I wrote up all my research in a post and why it is the best for Android: Android Vector Apps Write up for Android Tablet
- When done with the initial path making, I export the SVG to my GDrive, then open it on my desktop computer either Adobe Illustrator or Inkscape. Then I tweak all the lines to make them smoother, curve better, make sure that all the ends of the paths butt up against another path vs. being too far away to complete the puzzle piece cut out, etc. I also look for too skinny pieces, sharp bits, too small/too large/too long, etc.
- For whimsies, sometimes I add them into the puzzle at the drawing stage, and sometimes I leave blank spaces so that I can make them more precisely on the desktop.
Hope this helps, and I’d love to see what you come up with!
