One of my friends had on the cutest t-shirt the other day so I decided that I had to figure a way to make one for myself. She had gotten hers at an annual local craft show for about $25. So here's my method--it was so simple. And, what a great way to recycle an old t-shirt (can you see my grease spot below?)-- or buy a new one if you're making it for a gift. Now I'll be buying up all the t-shirts on clearance!
First, put the wax paper inside the shirt so the bleach won't bleed through. Next, fill your spray bottle with bleach (1/2 bleach/1/2 water mix)-you don't need a lot. My spray bottle sprayed more of a "stream"-next time I'm going to try more of a "mist" one. Tape your cross on the shirt-you don't even have to make sure the edges are straight.
Now, a small section at a time, spray the bleach about 1/4 to 1/2 inch to the side of the tape (it will bleed up to the tape and under the tape some, so this leaves extra room for bleeding). Spray a little at a time (DO NOT OVER SATURATE) ---wait to see how much it bleeds before adding more. Immediately dry section with your hair dryer and move onto the next. Let dry completely before washing. Grease spot gone! For an updated version click here.
