Stained T-Shirt refashion

A few months ago, I came across some colorful t-shirts for just $5 each. I grabbed 5 different colors, Diana looks awesome in anything but 'awesomer' in bright colors; or maybe mommy just loves color:)
My daughter has been very 'artistic lately', she has been writing and drawing and cutting whatever she can get her hands on, she was wearing this T-shirt on one of her missions. She is only 3 and I guess its a phase for her, hopefully it passes soon.

I like how this colorblock 'combo' turned out

So, this is how Diana refashioned her tee

We tried to watch off the stains but wasn't successful. So I cut off the stained part. Lucky the top was ok

Use the cut off tee to measure the replacement knit fabric. Sew on both sides as shown. After sewing along the sides both pieces should be of equal width. Then turn the striped fabric out, so the wrong sides are facing.

From the 'head side' insert the lower piece

Make sure the edges on both pieces are evenly aligned.

Use pins to attach the 2 pieces. Then sew around the shirt above the pins. Then sew the bottom of the shirt and you are done.

Isn't she the cutest thing EVER?! I just followed her around and got some cute poses.
