I love the June Tailor from Wal-mart, too! I drape my quilts on my dining room table. With the leaves in it's 4 x 8 so it works great. As for the sticky mess, I move all the chairs out of the way and "try" to keep it off the floor. I've found it mops up well with my steam mop. Since I hate to clean, basting quilts forces me to mop once in awhile!!!
My big problem last time was that I sprayed my arm. I had batting fuzz on my arm like you wouldn't believe!!
