batts with scrim (like warm & natural) are made more for machine quilting-
read the packaging- hobbs heirloom is a wonderful batt for hand quilting-
batts that say on the packaging-- recommended quilting every 2-4"---without scrim are the batts usually used for hand work-
wool batt is WONDERFUL FOR HAND WORK!!!
but if you just want something for practice- to learn pick up a hobbs 80/20 batt- they tend to be fairly inexpensive and very nice to needle.
