If the run is exclusively fleece, you may want to go a step coarser with your mesh, and of course, adjust your off-contact for the thicker fabric.
On multi color prints, shrinkage leading to lack of registration can be an issue since palette stick-um is not as easy of an operation as with T's.
So, many run them through the dryer prior to printing, or spin them under the flash.
Many, who even use a brush-on liquid adhesive for T's still use an aerosol web spray for fleece, and re-apply very often.
Those who use brush-on adhesive may rejuvenate with a damp rag just as often.
