Yup, I cross under and up through opposite side.
Image from Project Puppet Tutorial Page My standard stitch spacing is about 1/16", and I don't go in more than 1/16" from the edge (3/64" is typical, depending on the condition of the fleece edge). Again, I typically throw in a lock stitch (loop the thread back through) whenever the fleece is pulling apart, when I'm in a corner, or when I know I'm going to stop for a bit.
I start off with a quick twist knot from the back side of the fabric, and I use only SINGLE threaded stitches on fleece.
Perhaps the ladder stitch works better on "blizzard" fleece? I don't know, I don't use blizzard anymore.
