Lace Fabric Yardage: Buying the Edge, Not Just the Cloth
With most fabric you buy an area and cut what you like from it. With lace you are often buying a specific edge, and that edge decides where every piece is allowed to sit.
The Finished Edge Is Half of What You Are Paying For
Look down the two long edges of a piece of lace. On plenty of bridal and evening lace, one or both will have a scalloped border: a proper finished edge with the motifs completed rather than cut through. That edge is meant to become a hem, a neckline or a sleeve opening without being turned under at all.
Lace with a scallop on one side is usually called a single edge or border lace, and one with scallops on both is a galloon. A galloon costs more, and it can be the cheaper option overall, because you get two usable edges from a single length.
| Lace type | Usual width | Finished edges | Typical use |
|---|---|---|---|
| Chantilly | 36–45" | Often galloon | Bridal, overlays |
| Alençon | 36" | Usually one or two | Bridal, formal |
| Guipure | 44–52" | Sometimes | Bodices, structured pieces |
| Stretch lace | 54–58" | Often one | Lingerie, close fitting dresses |
| Curtain lace | 54–118" | Usually a lower border | Window panels |
The Scallop Decides Where Every Piece Sits
This is the part that catches people out. On plain fabric you shuffle pieces around to pack them tightly, turning one upside down to fit beside another. Lace with a scalloped edge takes that away, because any piece that needs the scallop has to sit hard against that selvage. It cannot move up, down or sideways.
So your layout has two zones: a strip along the finished edge reserved for the pieces that need it, and the plain centre for everything else. Plan the edge pieces first and fill in around them. Doing it the other way round usually ends with a beautifully efficient layout that has nowhere left for the hem.
When the Skirt Is Longer Than the Lace Is Wide
Here is the constraint nobody mentions until it bites. The scallop runs along the length of the roll. If you want it to be the hem of a skirt, the hem has to lie along that selvage, which means the skirt is lying sideways: its waist to hem measurement runs across the fabric width, not down the roll.
On a lace 36 inches wide, that caps your skirt at roughly 35 inches from waist to hem once you allow for the waist seam. A 40 inch skirt simply cannot have that scalloped edge as its hem. Not because of yardage, but because the fabric is not wide enough in the direction you need.
You then have three ways out:
- Shorten the skirt to fit within the width.
- Cut the scallop off as a separate border and apply it to a plain hem. You need as much length as your hem is long, so a 60 inch hem needs 60 inches of lace, about 1.7 yards. The rest of that width is still usable for other pieces, so it is not wasted, just committed.
- Buy a wider lace or a galloon, which may be cheaper than either of the above once you count everything.
Work out which of these you are doing before ordering. It changes the number more than any allowance you might add.
Budget for the Layer Underneath
Lace is mostly holes. Unless you are making something deliberately sheer, there is a second fabric under it, and that is a second yardage to work out rather than an afterthought.
Do not assume the two match. The lining is often a different width, which means a different layout and a different number of yards, and it has no scallop to work around so it lays out freely. Silk habotai is a common choice underneath, and the silk guide covers the narrow widths that come with it. Work the two out separately and add them at the end.
Left and Right Have to Mirror Each Other
On a large motif lace, a bodice front and its opposite side need the design to land in the same place on each. If a flower sits over one shoulder and the other side gets a gap, it reads as a mistake from across the room even to someone who knows nothing about sewing.
Matching pairs like this means positioning both pieces against the repeat rather than wherever they fit, so allow roughly one extra repeat of length for each pair you care about. Measure the repeat by finding one recognisable motif and the next identical one down the length. On a 12 inch repeat with three pairs to match, that is 36 inches of length before anything else. The pattern repeat guide covers measuring it properly.
