Did you buy a machine?
Or getting ready for your LA class/lesson?
Exciiiiiiiiiiiting!
I can't say that I've been there, done that, but for sure, doodling always seems to be mentioned. To me, what makes sense is to remember the "free" of FMQ, and not get hung up on repetition and precision at the start.
While I do not LA, but do FMQ on a DSM or S16, I find drawing on a design is helpful, but in reality, I let "free" win out and only use the lines for some guidance .... and let happen what happens as I FMQ along. Later, I get rid of those extra lines.
