I dyed my slipcover from white (which was way too white for my living room and changed the whole look with RIT DYE) 
THIS IS WHAT YOU NEED....
A FEW WEEKS AGO...I DYED ONE OF MY SLIPCOVERS FROM WHITE TO BROWN...CAME OUT GREAT SO THOUGHT I'D SHARE THE PROCESS...since I am ready to start another project...I recently purchased 20 yards of Muslin...I consider it to be the "Poor Man's Linen" it gives you a lovely wrinkled look much like that of Linen...
MUSLIN can be purchased in very wide widths which is another reason it's so fabulous for making bed covers. The Muslin I purchased was in a 90" width.
When I purchased Muslin for my bedroom I purchased it in a 60"width and ended up adding 2 seams down the top to accommodate the width of my king-size bed.
**Note I washed the MUSLIN twice to make sure that it shrunk before I actually started sewing and dried it in medium dryer.

**Note***I once did not prewash and the MUSLIN shrunk some 3-5" ...so from now on I always pre-wash.
1. Pre-wash you fabrics to allow shrinkage or allow extra for sufficient shrinkage.
2. Cut your fabric in sections of 3-4 yards for large projects.
3. I used Rit Liquid Dye (from my local Grocery Store) approx $5.50 a bottle. A bottle will dye 2 lbs of fabric.***You will also need to purchase SALT to help set the color in cotton, linen, rayon, ramie and blends 1 cup is recommended to dye bath.***Of course read the bottle for specific directions and also you can acquire additional info at their website **DO NOT POUR DYE ONTO FABRIC BUT LET IT DILUTE IN THE WATER***WEAR RUBBER GLOVES***
4. I DID MY DYE BATH IN THE BATHTUB SINCE I HAVE A STACKABLE WASHER AND DRYER. TAKES APPROX 30-60 MIN ***CONSTANTLY AGITATING (STIRRING) TO SET COLOR (MAY USE WASHER) I PREFERRED TO USE BATHTUB BECAUSE SLIPCOVER WAS SO LARGE AND THERE WERE SO MANY PILLOWS AND CUSHION COVERS.

**BEFORE YOU ADD THE DYE TO WATER MAKE SURE YOUR FABRIC IS COMPLETELY WET THIS WILL HELP THE DYE TO KEEP TO IT'S TRUE COLOR.
FOR AGITATING I USED A PIECE OF BOARD TO HELP STIR ALSO LIFTED AND TURNED THE FABRIC ***YOU DO NOT WANT THERE TO BE A MISSED AREA...Now you are probably wondering what I did for clean-up i used a diluted mixture of water and bleach and dye came right off (In fact I don't recommend this but it even came off of the grout where a piece splashed onto my new subway tile.
**note** i was so scared to do this for fear I would ruin my slipcover but if I had it to do over....I'd do it again! 
THE SOFA PIC DOESN'T LOOK AS WHITE AS IT DID IN PERSON. trust me it was bright white.
This was a better pic TO SEE HOW WHITE IT ACTUALLY WAS AND NOT ONLY THAT BECAUSE IT WAS MADE OUT OF COTTON DUCKING IT LOOKED LIKE A WHITE SHEET. It was easier to change the slipcover than to change everything else...
