I had my husband buy me some long boards and cut them down to 6' long. I clear out my kitchen island (I love the height). Start with the backing and roll it up with the right side down.
Smooth out the quilt as you go and wrap fairly tightly. Then wrap your top with the right side up. forgot to get a picture of that). Start the basting process by laying the bottom out and smoothing it nicely.
Lay the batting on top of it lining up the bottom and sides, smoothing a you go.
Lay the top on top of that and unroll it towards the back, smoothing as you go.
Pin baste the exposed area. When you run out of room, pull the excess batting over the top and slide to the front of your surface.
Unroll the backing, flip the batting back on top and then unroll the top over it all. Make sure all layers are smooth of course.
