Sit up higher than you usually do so you can see better and won't slouch.
Try FMQ in a straight line, from side to side. Once you have mastered that, then try going the opposite way. Then meander or do swirls. I was taught with cursive e's and l's - you can try alternating also. It takes time and practice. Have fun! I made a lot of quilts for my dog when I first started!
