Here is a very quick tutorial about making a quilt sandwich–which can be super satisfying. First it is essential to clear a large space to spread out. Spread your quilt back, right side down, on the floor. Tape the edges (I use blue painter’s tape) to the floor so the fabric is smooth, but not taut. Pull off any stray threads.
Next unfold your batting and, starting from the center, gently smooth out any wrinkles. The batting sticks to the fabric so you may need to lift the batting gently to smooth out some wrinkles. Once your batting is nice and smooth, trim any excess that extends beyond the edges of the backing.
Then, lay your quilt top, right side up, on top of the batting. Your quilt top will be smaller than the backing and batting so you should be able to position it neatly. Again, starting in the center, smooth your quilt top onto the batting gently pushing any wrinkles to the edges. Finally, you can either baste or pin your sandwich together. I prefer pins because I find pinning (with curved quilting safety pins) keeps my sandwich smooth. It is also faster than basting. Sometimes I baste the pinned quilt after I take it off the floor. The basting makes it easier when you are doing the quilting. Here is my quilt–all sandwiched together and ready to go.
