I have a navy blue and tan stripe crouch. Is there anyway I can use dye to make it navy? Can I use Rit dye to dye my carpet?

Dear Christy,
Sorry, you cannot dye your sofa or the carpet. You could conceivably make an interesting art project out of the sofa by painting with dye or fabric paint. However, if you want an even color, there is no chance that it will come out like that. Get some slipcovers in the new color or look for a new sofa.
I have successfully dyed all-cotton bath rugs with reactive dyes. But synthetic carpet or rugs will not take dye at all and will result in a big mess.
Good luck with redecorating!
Jennifer
