One day while perusing Pinterest, I found this post from The Prudent Pantry on a green way to get rid of the stains. I tried it on one shirt, and whaddya know, it worked!
So one evening, I pulled all the white shirts out of my closet. Using an old plastic party cup, an old toothbrush I set aside for cleaning purposes, and then the Dawn, hydrogen peroxide, and baking soda, I whipped up a batch and covered the armpits and necklines of all the shirts. (I'll spare you the 'before' pictures.)
I let them hang in my bathroom overnight, and washed on cold the next day.
Not sure why it has to be blue Dawn (most posts I found specify blue) but who cares?! It works!
Meanwhile, I've been working on this crochet camisole from FreePatterns.com with some hemp yarn. Turned out super cute, just took longer than I expected to finish, with all the little stitches. Though sleeveless, the hemp yarn is a little heavier than I imagined, so this might be more of a fall top.
And in case you haven't seen the FB post, I'm having a big clearance sale in my Etsy store as I want to focus more on stitch projects and patterns. Be sure to check it out!
