Print and Pattern Matching: Plaids, Stripes and Repeats

Every patterned fabric has a repeat, the distance over which the design starts again, both horizontally and vertically. Matching depends on understanding the repeat, because to align a pattern across a seam, the corresponding pieces must be cut at the same point in the repeat.

Plaids also fall into two types. An even plaid is symmetrical in both directions, with the same sequence of bars left to right and top to bottom, which is far easier to match. An uneven plaid is asymmetrical, so it has a definite direction and requires careful, often single-layer, cutting to keep the sequence consistent.

Matching consumes fabric, because you must shift pieces along the cloth to align the repeat, which leaves unusable gaps. The standard allowance is to add at least one full pattern repeat for each major piece you intend to match; for large plaids this can mean half a meter or more of extra cloth.

This is one purchase where running short is unforgiving, since you cannot match what you do not have and the dye lot may be gone. Buy generously, and choose patterns with fewer pieces and seams when working with a bold plaid to make matching achievable.

Cutting plaids and large prints is almost always done in a single layer so you can see exactly where each piece falls on the design. Decide where the dominant lines should sit, conventionally placing a prominent bar at center front and center back and balancing the design symmetrically across the body.

Mark the key match points, such as side seams and shoulders, on the pattern and align each adjoining piece at the same point in the repeat. Cutting one piece, then using it to position its neighbor on the matching part of the design, is the most reliable method.

It is not always possible to match every seam, so prioritize the most visible. The eye notices certain seams far more than others, and skilled makers focus effort where it counts.

• Center front and center back: most visible, match first
• Side seams at the hip and bust level: prominent and worth matching
• Front pockets and patch pieces: should blend into the surrounding cloth
• Sleeves at the front armhole notch: visible and improve a tailored look
• Less critical: under-sleeve seams, hidden facings, and areas behind the arm

1. 1.Lay the fabric in a single layer, right side up, and identify the repeat in both directions.
2. 2.Position the first piece, marking which line falls on key reference points.
3. 3.Cut the first piece, then lay it on the fabric to position its mirror or adjoining piece on the matching part of the design before cutting the second.
4. 4.Transfer notches and a few match marks across the matching lines so you can realign exactly when sewing.

Even perfectly cut pieces can shift while sewing and lose the match. To prevent this, hand-baste the seam first with the layers aligned at the pattern lines, or use a slip-basting technique that lets you fold and pin the match from the right side before stitching from the wrong side. A walking foot also helps by feeding both layers evenly so they do not creep.

When you bring a Minerva Patterns file to life in a plaid or bold stripe, matching the pattern across seams transforms the result. The precise drafting gives you accurate seam lines to match along, and the matched print is what makes the finished garment read as truly professional.
