DIYP reader, Jerry, made a great comment on the process of making a tie-dye muslin backdrop.
It appears that Jerry remembers those happy days from when Tie-Dye was in fashion, and hair was the best show you can catch on Broadway.
Jerry tells that back is those days Tie-Dye shirts were the thing to wear and making Tie-Dye shirts was a common art. (Well, Digital cameras were very expensive then – they cost was just about a time travel ticket plus 1000$).
To spice up the color of a fabric, Jerry spiced up the Tie-Dye process. After the dying process has finished, but before removing the cord and hanging out to dry, you place the fabric in a fixer container.
