The Top 10 Mistakes

#	Mistake	How to Avoid It
1	Not running a tension test first	Always stitch a 4–6 inch test on a scrap sandwich before starting the quilt Test First
2	Using a dull needle	Change the needle every 8–10 hours or every 2–3 quilts. Needles are cheap; bad quilting isn’t.
3	Loading the backing unevenly	Measure and check squareness before loading the batting. Fix the backing before loading anything else.
4	Skipping machine cleaning	Clean lint from the bobbin area after every single quilt. 60 seconds prevents most tension problems.
5	Quilting beyond the manufacturer’s maximum spacing	Know your batting’s maximum quilting distance. Exceeding it causes batting migration after washing.
6	Running out of thread mid-quilt	Check thread levels before starting. Have a second cone of the same color on hand for long quilts.
7	Starting without holding thread tails	Hold both top and bobbin tails for the first 3–4 stitches to prevent bird’s nests under the quilt.
8	Not squaring the quilt top before loading	Check that the top is square before it goes on the frame. Crooked tops cannot be fixed after loading.
9	Changing thread without re-testing tension	Every thread brand and weight change requires a new tension test. Never assume settings transfer.
10	Taking customer quilts before you’re ready	Quilt 20–30 personal quilts before taking customer work. Build confidence first.

▶ The Pattern Most longarm mistakes come from skipping preparation steps — the tension test, needle check, machine clean, thread tail hold. The preparation before the first stitch determines 80% of the result. Slow down before you start and the quilting itself becomes easier.

Frequently Asked Questions

What is the most common cause of skipped stitches?

A dull or bent needle is responsible for the majority of skipped stitches. Change the needle first before adjusting any settings. If skipped stitches persist after a needle change and complete re-threading, check needle size compatibility with your thread weight.

How do I know if my quilt top is square before loading?

Measure diagonals corner to corner. If both diagonal measurements are equal, the top is square. If one is longer, the top is off-square and needs to be corrected before loading. A few minutes fixing squareness saves hours of fighting a distorted quilt on the frame.
