A Christmas sweatshirt that exists once

Yes, and not as a figure of speech. Ice dyeing works by mounding ice over folded fabric and sprinkling dye powder on top. As the ice melts it carries the dye down in a path nothing controls. Two pieces folded the same way, in the same batch, in the same dye, come out visibly different. The photographs on each listing are of the actual piece — never a rendering.

Ordinary tie dye uses liquid dye squeezed onto tied fabric, which gives you the hard-edged spirals everyone recognizes. Ice dye uses dye powder and a full day of melting ice, so the color breaks apart as it travels — a crimson will throw off pink and rust at its edges, a pine green will split into teal and gold. That is why these look like watercolor rather than stripes.

Crimson red and pine green, with the white of the blank left showing where the ice sat longest. Because the two dyes split as they melt, most pieces also carry teal, rose and a little gold. Red and green tie dye done this way reads as Christmas without a single snowflake printed on it — though several of the printed designs are dyed onto this same colorway.

Yes — order them in the same batch and they will be dyed together in the same dye bath, so they belong to each other as a set. They will not be identical, because nothing here is identical, but they will read as a family. Order them in different batches and the match is looser.

Every piece is dyed by one person, Maria, in York, Pennsylvania. Nothing is printed, nothing is drop-shipped and nothing is finished by a factory. She has been doing it since 2015.

Machine wash cold, inside out, and tumble dry low. The dye is fiber-reactive and fully rinsed before it ships, so it is bonded to the cotton rather than sitting on top of it. It will not bleed onto anything in the wash.

It comes off the dye schedule after Christmas and does not return until next December. When a colorway retires we move it to the archive and stop dyeing it — that page is the receipt.
