For a long time I boycotted using plastic baggies (I also avoid like the plague tin foil and plastic wrap for various reasons I'm sure you can guess). But more and more these days I find need for plastic bags: for wet bathing suits and messy snacks and the such.
I have to admit, though I really hate to, plastic bags make life easy in certain situations. But I've successfully found replacements like my baggu bags for groceries and snack traps for after school fruit type snacks at the playground.
Luckily, my friend Maren Briggs is beyond crafty and supertalented. She made me some amazing reusable baggies from recycled fabric scraps. She sews amazing kids clothes for her etsy site with vintage fabrics and with the scraps from that she makes baggies. How amazing?!? And totally earth friendly and eco-conscious, I love it!
My bag is filled with her baggies compartmentalizing my life. It's brilliant!
