A few months ago I learned a great trick to make this entire process easier and helps with minimizing the bumps and wrinkles on one side or the other.
Have you ever used two eight foot 2x4's and painters tape to make your sandwich? A long table or space to spread out the length of the 2x4 is needed but no need to spread out and crawl on the floor to baste this baby.
lay out each 2x4 and unroll slowly, adding batting, begin to smooth out wrinkles as layers are basted and you finalize your quilt sandwich
Now for a break to shovel the drive way while the sun is shining.
Have a great weekend!
