I'm using polar fleece (I think that's what it's called. It's really thick, almost spongy) as a backing for a baby quilt. I have to use a white batting, probably Warm and Natural White, in between because the colors of the backing will show through onto the front otherwise.

I'm not sure if I need to use special care loading the fleece. Someone told me be careful not to stretch it too much, but is there a better direction to load it? I'm planning to do an all over stipple. I'm still new to long arming, so I welcome any advice/input. As always, thanks in advance!
