simple colour gradation using MX

If Nothing Else...

asked ..what is the best dye product to use when dyeing silk a solid color? Acid dyes require very hot water and I fear the silk will shrink or worse.

I replied in the comments section of my blog but wanted to post a picture showing my preferred technique as used on china silk to the left and pima cotton on the right.
there is a slight difference in depth of shade with the silk in this case as it is a much lighter fabric than pima - fewer dye receptor cells.
