Quilt top should be trimmed down to final finished size.
Make sure that your quilt is square. All corners must be 90 degrees and the backing needs to be square as well.
Don't trim the salvages off of your backing.
You should stay stitch around your entire quilt to ensure that seams do not pull apart if you have a lot of seams on the edge. If you just have a few seams in borders, please stay stitch just over each seam.
Use safety pin to mark the upper left corner of the top and upper left corner of the backing of your quilt.
Remove all excess threads from the front of the quilt top.
Snip off all dark colored thread from the back of your quilt top that might show through the front after it is quilted.
Snip off all loose threads and check for any holes in seams, loose seams or anything that might catch on the machine as it passes by.
The quilt top must lay flat. Measure your quilt top across the top, bottom and center. All three measurements should be the same. If they are not, there is a strong possibility that there will be puckers in your finished quilt. I cannot "fix it" with quilting!
Batting and back need to be at least 8 inches larger (4 inches on each side including top and bottom) than the quilt top.
Leave the top, batting and backing all separate. Do not baste the layers together.
If you washed the fabrics for the quilt top before sewing, please wash the backing as well. You will be much happier with the finished product after the first washing.
