i've used both many times- the minkee on the back of my queen sized quilt is so soft and FABULOUS! I made that one- then my granddaugters decided they really wanted new quilts with minkee on them- so they all 3 got new quilts with minkee- it is so wonderfully soft---(the girls call them 'get naked blankets'--they love wrapping in them right out of the shower)
I've use fleece numerous times too- i like fleece for utility warm quilts- it wears very well, and is oh so warm.
i do use batting (most of the time) i have made a couple without batting- but that was 'by request'
i like the 'loftiness' of the added batting-
i use good quality- double sided fleece- and all kinds of different minkee's- the minkee is so soft...
i don't know why one person said to only use it for baby quilts- i've used it on numerous queens, and 2 kings.
i do take it outside and shake the heck out of it to get rid of the cut edge flaking---once that is taken care of it['s great to work with.
