I have been FMQ for all of 2 days now. For me, tracing an exact line was really hard to keep a smooth line of stitching but following a general direction worked easier.
My tip would be to start off working in short increments. After even 10 minutes I get tired/frustrated and need to go do something else for a while and come back to the FMQ.
Here is a pic of my daisies, which seem to get happier as I went along. Maybe I will be ready to use them on the tabletopper I want to give my MIL by August!
