Great advice. l but I will say slllllllllllooooooooooooowwwww down. Work on getting the tension mastered. This can be frustrating in the beginning.
Once you get that get a very busy print top and go for it. If you get lost the quilting police will not arrest you if you cross over a line of stitching. I picked one easy pattern and used that until I could do it in my sleep. it is still my go to for charity tops.
It is a line I call a vine. I go from the top of one section to the bottom adding leaves along the way. Then do a wiggle line to get to another part and do the same thing going up. I never get lost as it is just up and down across the top.
I have a great combo of thread and bobbins that I stick with, I do not quilt for $$. I use Essential Pro from Connecting Threads and Bottomline pre wounds from Superior. I did not get a bobbin winder with my used HQ16.
