This Tie-dye Racerback T-shirt aka Bikini Cover-up – project is one for my stash! I get so many free t-shirts at all these trade shows that I wonder what to do with them at time. This is a great way to use them, provided that there’s not too much advertising on them at the the front that must be covered.
Tie-dye racerback t-shirt

As you can see, you don’t need much beyond a white t-shirt and a tie-dye kit which you can buy at Amazon.
These visual instructions on how to tie-dye were on AdventuresofaMiddleSister.com. Photo credit: Allie Holcomb. This site no longer exists. The visuals are pretty self-explanatory. However I know that all tie-dye kits come with their own instructions. Be sure to read them, although they are all pretty similar:
How to Tie Dye Instructions, step by step
1: First wash your fabric, to remove fabrication residue.
2: Prep the fixing water. (Optional: I have done Tie-dye projects without this step, and just running the final product in cold water instead.
3: Soak your fabric, and squeeze out the excess water.
4: the fun bit: get a mountain of elastic bands, and go tie folds and twists
5: Mix dye colors and put them in spray bottles
6: Apply your dye over your tied fabric.
7: Put in a plastic bag and cure overnight.
8: Rinse in a metal sink in cold water, and let t-shirt dry.
Ready to wear!
(Ok. You are right: This is the most fun step!)
