Your top should be pressed and loose threads clipped (or they may show through the top after quilting). You can hang your top on a hanger or place it in a CLEAR bag for drop off. Don't use black garbage bags. Bad things happen with black garbage bags. See through is always best.
Wide Backs are awesome! Did you know that pre-washing your wide backs will give you better tension? The new wide backs have a lot of "stuff" in them to help them to last longer on the store shelves. This sizing material also makes the needle on the longarm want to "pop" through the backing rather than slide through. I don't make you wash your wide backs but you can if you want he best tension. Wash, iron, and hang your backing on a hanger or fold neatly in that same CLEAR bag that your top is in. Your wide back should be 8" bigger in all dimensions than your quilt top (so 4" bigger on each side and top and bottom).
Pieced Backs - I require your backing to be 8" larger than your quilt top (both on the top and sides). See my calculator if you are unsure what size to make your back. When you piece your backing fabric please try to press your seams open or to one side. If you join your fabric on the salvage edge please cut the salvage off. That bit of salvage is very strong and will affect how your backing rolls on on my leaders. Salvage edges are awesome on the top and bottom of your backing but are nasty in the seams. The salvage edges wash differently than the rest of your fabric and they also have less give. That affects how your quilt finishes. So, just take those out of the seams!
You can bring your own batting or I can sell you batting. The brand or type of batting you use is totally your choice. Your backing should also be 8" larger in all dimensions than your quilt top. The neater your batting is the easier it is for me to quilt. If I have to steam or iron your batting then that will be an extra fee. Note: the backing calculator will work for your batting as well.
You can drop your quilt top/batting/batting off at Cotton Candy Quilt and Sewing during Covid. You may also ship to me if you are not local. If you ship, please place your items in a clear bag and then place in a shipping box. The bag protects the contents as sometimes the boxes can come partially opened. If you are dropping your quilts off to me on my porch (sorry not letting you visit right now) or to the store please clearly label the outside of your package with the following: Your Name, My Name, and your Cell number. Dropping at my home: email me for my address.
