I took a class recently and what I found most informative was
1. Needle size and type - Size 12 Topstich, this is for either a quilting machine on a frame or your everyday machine.
2. Thread size and type - good quality thread. For dense quilting, use thinner thread (100wt) use 40wt for wider quilting.
3. Mark your design on the quilt using a water soluable marking pen, go slow and be patient.
