Indicate whether this is a bed quilt, wall hanging and if it is directional. Attach this information on a piece of paper pinned to the quilt indicating which area you consider to be the top of the quilt (if applicable).
If your quilt does not lay flat or is not square, I cannot guarantee that it will do so after quilting.
Your quilt backing should be 8 inches wider and longer than your quilt top, which is 4 inches more on all sides. For example, if your quilt measures 100 x 100, then the back must be at least 108 x 108 inches. If your quilt measures is 50 x 60 then the back must be at least 58 x 68 inches. The extra fabric is required to clamp it on my longarm machine to be quilted.
Trim off the selvage before you piece the back seams. The selvage shrinks differently than the rest of the fabric when it is washed. You can leave the selvage on the outside edges of the back as they will get cut off when your trim the quilt after it is quilted.
Straight & squared edges are also required to clamp it to the longarm machine.
I keep Hobbs 80/20 in natural and black, Hobbs wool batting and Legacy 100% cotton batting in stock and prefer using these to quilt. However, you may provide me with your own batting except bamboo batting and very lenty batting. It needs to be 8 inches wider and longer than your quilt top.
