if you are doing free-motion quilting the feeddogs need to be down-and you need to use a hopping/darning foot-
if you are doing straightline quilting (stitch in the ditch/ cross-hatch) you can use a walking foot with feed dogs up (engaged)
and don't start right out with a quilt----put together some practice (sandwiches- top, batting/backing) and do some practicing before trying to quilt something (real)
it takes practice, practice, patience, and more practice before you will be ready to attack a quilt-
we used to purchase a bolt of fairly inexpensive muslin and when we wanted to practice we would cut (2) 2 yd pieces- load them up for a top & bottom with inexpensive (what ever was on sale) batting- thread machine with some colored thread (top & bobbin) so we could see what we were doing----& practice---
