community of dyers

I simply do solution of soda 250g per 1l. Then I stuff the dyeing pot with fabrics, dye solutions, soda solution in sub sequent manner to have just enough of everything as it fills up.

This is what I get this way.
Bigger resolution image is here. (I prefer rather subtle changes in shade, not too much contrast, that's why I prefer to add soda "on the run" and not pre-soak and I pour in tone-in-tone dyes)

When I first started using the LWI method, I added the dissolved soda ash solution to the dye bath about an hour after I applied the dye. More recently, I tend to pre-soak my piece in soda ash solution for about 15 minutes, squeeze out the excess soda ash, scrunch my piece into a small container, then apply the dyes and batch for about an hour. I think submerging the dyed fabric into a bath of soda ash might be too much soda ash, but as with anything, it's worth a try to see what kind of results you would get. You might want to do a side-by-side experiment comparing between submerging and pouring soda ash over, just to see which method gives you a better result. And do let us know how it comes out if you try!
