Petersham

Cotton petersham ribbon

Grosgrain that bends. The scalloped edge lets it curve when steamed, so it follows a hat brim or a waistband instead of fighting it. That one property is what hat makers buy it for.

Navy petersham ribbon curved into an arc above a flat length of grosgrain

What it is

Why it curves and grosgrain does not

Look at the edge. Petersham finishes in small scallops rather than a straight selvedge, and those scallops can open on one side and close on the other. Steam it, ease it round, and it takes a curve and keeps it.

Ordinary grosgrain cannot do this. Forced round a curve it buckles, and the buckle shows through the outside of the garment. It also costs about 40% less, which is why people order the wrong one — usually the cheap one when they needed this.

Rule of thumb: if it has to follow a curve, it is petersham. If it stays flat and straight, ordinary grosgrain will do.

Ordering

What an order looks like

Colour

Dyed to your shade — a Pantone number, or a piece of the ribbon you use today. The whole order is dyed in one batch, so the last metre matches the first. Approval takes about five working days.

Quantity

Minimum 500 m per colour. A colour made specially for you carries a 3,000 m minimum for that colour, as does any width outside the runner sizes.

Packing and delivery

100 m to a roll on a paper core, or 25 m and 50 m spools if you sell it on. Orders ship in 6–9 days up to 20,000 m, 10–14 days to 50,000 m, and 16–20 days beyond that.
