Rit Dye Liquid Dye, 8 fl oz, Royal Blue, 3-Pack

This makes a very nice, strong and bright blue - at least, on cotton fabric, stovetop with simmering water, and increasing strength of dye solution. Unfortunately, the color fades after several washings, but is still acceptable. Maybe colder wash water?

I used this to dye a slipcover. Second time Ive done it. Sofa is in a condo at the beach and fades from the sunlight. I have to re-dye every year. The fixative does not work as it is described; that is, it still fades quickly. However, its a better solution than a new sofa. It looks good after redyeing for about 6 to 8 months, then the fading becomes obvious. Easy to do in a washing machine. Machine cleans up like new and is not stained.

Same as described.
