D.I.Y Dyeing your carpet..

[I heart the SSS]

does it smell??

Not at all. Once it's dry it's pretty odourless.

Looks to be a good idea mate. Results look good too. Is the texture/feel of the carpet still the same?

Feels the same, it's a dye so it stains your fabric, not like the paint on stuff which leaves a spikey texture..

wow this is quite interesting
i also want to know if the dye will run when wet and
wonder how would red turn out

AS said above, it's a dye so it won't run. Red would look good, Just use the colour remover dye stuff prior to using the red !
