I found this blog that had a bunch of links to other blogs that give you a ton of different ideas for upcycling t-shirts:
And ladies, your eyes are not failing- there IS a link to make your own maxi pads! Finally! Your days of using old rags and tube socks are over- you can finally follow a pattern to make super cute reusable pads! Holy crap, I think I barfed in my mouth just typing that. That started out as a joke but I think I grossed myself out. But that blog has a lot of other links that could give you inspiration.
My personal favorite, and the one that I found months ago, is this site:
How pretty is this shirt? And when you read her blog, you'll see she used 2 t-shirts that she bought for a dollar each and came up with this. Let your jealousy course through you now and get it over with. You'll be addicted to this blog and the things she makes. I'm a little nervous about giving you the link because it makes my blog look like monkey poop. Come back, okay?
Step 1: Identify which crappy t-shirts you don't mind sacrificing to the sewing gods. Here's my plethora of crappiness I have to choose from:
You like the gratuitous picture of the cat licking himself? I thought so. Skipper is so classy like his mama.
I decided to use the dark green shirt that I got from Old Navy for $5 about 3 years ago. Bobby refers to this shirt as "that shirt you wear all the time that you think looks good".
Needless to say, I will use Bobby's shirts as needed. Maybe for those maxi-pads. Anyway, I like the fit of this shirt but it's a little too low cut in the front and honestly, it looks like a $5 shirt. So I don't have anything to lose here.
Step 2: For the accent ruffles, I am going to use this old black shirt I got from Target a long time ago. I know the example shows ruffles made from the same color t-shirt but tough crap. This is whats I gots. For your shirt, try to pick one without so much cat hair.
I'm going to be doing my ruffles a little differently than the example so instead of doing my loose stitch at the top of each strip to create the ruffle, I do it right down the middle. Then I gather the fabric until the ruffle looks the way I want it to look and I lay it around the neckline of the shirt.
