Longarm quilting is a way to finish a pieced top by stitching it to batting and backing with a specialist machine. If you plan to use a finishing service, contact the quilter before buying or cutting the backing. Their intake instructions determine the size and preparation of each layer.
Use our quilting guide for the complete project order. Before sending the layers, measure the top, agree on the design and ask what preparation the service needs. Keep those decisions with the quilt so the quilter can match them to your project.
Longarm finishing starts with the intake sheet
Ask your quilter for their preparation requirements. They may specify backing margins, seam prep, batting choices, thread choices and how to mark the top edge. Save the intake sheet with your project paperwork so you can check each requirement before packing.
Handi Quilter's backing guide describes extra backing around the top for longarm work. Treat your own quilter's needs as the cutting plan. Different margins in two guides are a reason to ask before cutting.
Tell the quilter the planned use of the quilt and the kind of stitching you like. A soft everyday quilt and a densely stitched display quilt may lead to different design discussions. Show an example of the general look if that makes your preference easier to explain.
Measure the top after its final prep
Lay the top flat and measure its width in more than one place. Do the same for its length. Record the measurements and any difference between them. If a border ripples or the top has a fold that will not lie flat, ask the quilter before packing it.
Measure the sewn top even when the pattern gives a finished size. Added borders, wider seams or a different layout can make your top larger or smaller than the pattern example. Calculate the backing from the fabric that will go on the frame.
Photograph the whole top in good light. Keep a second photo that shows the planned top edge. The pictures give you and the quilter a common reference when discussing the design or a directional backing print.
Calculate backing from the requested margin
Suppose your completed top measures 48 by 60 inches and the service asks for 4 inches extra on each side. Add 8 inches to each overall size: the minimum backing rectangle becomes 56 by 68 inches.
If you select fabric with a measured usable width of 108 inches, a 68-inch length provides that rectangle with room across the width. The length is 68 divided by 36, or about 1.89 yards. Choose enough extra for the real cutting and prep needs after checking the service's instructions.
If the usable width is only 42 inches, one width will not cover 56 inches. You need a pieced-back plan, with seam allowances and print direction worked out before ordering. Ask the quilter about seam orientation and prep rather than making a bulky seam in an awkward position.
These sizes illustrate a particular request. Replace the top size, margin and usable width with your own project measurements. The batting guide helps you choose the middle layer.
Choose the design and density before packing
Ask whether the service offers an all-over design, work placed in individual blocks, or both. Discuss the look on the real top. A busy print may show stitching differently from a large plain area, so ask to see sample quilts with similar fabric contrast.
Confirm how the design will face on a directional top. If a motif has a clear upright direction, mark the top edge using the service's method. Ask whether the quilting continues uniformly over the borders or changes there.
Density is another decision to make in words and examples. Explain the feel you want and let the quilter match it to the selected batting's needs. Keep the decision with the thread color and design name so all three refer to the same project.
Keep backing, batting and top separate as requested
The Handi Quilter prep booklet says not to baste layers together before longarm loading. Follow the service's packing instructions and label the individual layers as requested. Ask whether the quilter provides batting before buying your own.
Write down the batting product name as well as its fiber content. Stitch spacing and care directions belong to that exact product. Keep the package label with the batting so the quilter can check those instructions before loading it.
Check the back of the quilt top for loose threads that could show through lighter fabric. Use the pressing and seam prep the service asks for. Before taking out a seam or trimming an uneven edge, send a photo and ask the quilter how to proceed.
Make a one-page handoff note
Include your contact details, the top's measured sizes, the marked top edge, the selected design and the thread-color decision. Add the batting name and identify the backing that goes with the top. Keep a copy for yourself.
Ask where to place the handoff sheet and how to label the layers. Keep pins, loose tools and extra scraps out of the parcel unless the service requests them. Check that the quilter can identify each piece and match it to the instructions.
Confirm the return stage. Will the quilt come back trimmed? Will the raw edge still need binding? If you want to finish that part yourself, our machine binding guide takes over after quilting.
Check the quilt when it returns
Spread the quilt out and compare it with the handoff note. Look at the design direction, the thread choice and the whole stitched surface. Contact the quilter with a clear photo if a point needs discussion, before trimming away margins or washing the quilt.
Keep the care details for both fabric and batting with the finished project. Save the handoff sheet too. When planning another quilt, you can check which backing worked, which design you liked and what prep saved time.
If you want to learn the machine workflow yourself, read the long arm machine buying guide. Continue piecing on a suitable beginner quilting machine while deciding how much finishing work to bring into your room.
Verdict on longarm: agree on the handoff before cutting
Contact the quilter early, measure the real top and calculate the requested margins. Record design, thread and finishing choices together. Clear prep lets the service spend its time on the quilting you chose and gives you a predictable next step when the project returns.
FAQ
What does longarm mean in quilting?
It refers to quilting layers with a specialist longarm machine, often on a frame. A quilter may offer this as a finishing service for a top you have pieced. Ask which prep, design and binding tasks are included so that you know what comes back ready to use.
Should I baste a quilt before sending it to a longarm service?
Ask the service first. Frame quilting commonly loads the layers separately, and Handi Quilter prep guidance says to keep them unbasted. Follow your chosen quilter’s intake sheet because their frame and process determine how they need to receive the project.
Does a longarm service also bind the quilt?
Some services offer binding as a separate option. Confirm whether the return includes quilting only, trimming, binding attachment or a fully finished edge. Make that choice before sending fabric so the quilter can tell you how much binding material to include.
