How to Load a Quilt on a Longarm — Step-by-Step Guide

Loading a quilt on a longarm frame is the most important skill in longarm quilting — a badly loaded quilt cannot be fixed by good stitching. Here’s the complete step-by-step guide to loading your quilt back, batting, and top correctly every time.

Loading Steps in Order

Step	Action	Key Tips
1	Attach quilt back to leaders	Right side DOWN • Center on frame • Even tension Start Here
2	Roll backing onto take-up roller	Even, smooth — no tucks or folds
3	Float or pin batting	Extend 3–4" beyond all edges of backing
4	Float quilt top	Right side UP • Square to backing • Smooth completely Critical
5	Pin sides to leaders	Every 4–6" • Equal tension both sides
6	Check squareness	Measure diagonals • Equal = square
7	Test stitch on scrap	Always run tension test before starting the quilt

▶ The Most Important Rule The quilt back must be perfectly square and under even tension before you load anything else. If the back is crooked or lumpy, the entire quilt will be crooked. Spend 80% of your loading time getting the back right.

Common Loading Mistakes

Mistakes to avoid

Loading back too tight — causes distortion
Loading back too loose — causes ripples and tucks
Not floating the top — causes puckers
Skipping the squareness check
Skipping the tension test

Signs of a good load

Back lies perfectly flat under even tension
No ripples, tucks, or raised sections
Diagonals measure equal (quilt is square)
Top lies flat with no excess fabric bunching
Batting extends evenly beyond all edges

Frequently Asked Questions

How big should the quilt back be for longarm loading?

The backing should be at least 4 inches larger than the quilt top on all sides — 6–8 inches is better. This provides enough fabric to attach to the leaders and still have overage on the sides for pinning. A backing that’s too small cannot be loaded properly.

Should the quilt back be pre-washed?

If the quilt top fabrics are not pre-washed, don’t pre-wash the backing — everything should shrink together on first wash. If the top uses pre-washed fabrics, pre-wash the backing to match.

What is “floating” the quilt top?

Floating means the quilt top is not attached to any leader — it lies on top of the batting and is held in place by basting or pins at the top edge only. Floating allows the top to move freely as you quilt, reducing the chance of tucks forming underneath.
