Basic hem with fleece.
I start with an overcast on raw edges, not necessary with fleece, does not fray. I like to have a finished look on the inside of the garment.
Then do a single fold to the inside of the garment, usually a 1-inch hem on a hoodie jacket. Then flip to the front of the garment and top stitch, with fleece, I use the lighting bolt stretch stitch for topstitching.
In general, I run through the machine twice, instead of using a twin needle. No chance of tunneling that you sometimes get with a twin needle.
