This is the hoop I prefer for hand quilting:

It is easy to adjust to any angle and it leaves both hands free for quilting.
If you use a hoop, don't make the beginner's mistake of hooping the quilt drum tight. You want about a fist's width of "give" to allow you to manipulate the quilt along with the needle.
