Love the way you think! I have been seen in my footie pajamas (LOVE 'EM) & rubber boots out collecting eggs when I first get up...yeah ALL the neighbors know I'm crazy, but I'm good with it.
In answer to your question, Lyric, LOTS of old shirts (whether tanks, t's, whatever) is a MUST in FL. In the summer you will sweat yourself to death. I recommend t's rather than tanks at that point so you have a sleeve to wipe your face on when your hands are full! lol I was lucky when my boys moved out; they left stuff they didn't want but were too lazy to do anything with. I kept some of the ratty t's to farm in & donated the rest to Salvation Army. I also visit Walmart right after the major holidays--you know how they have t's celebrating them? I just got about 7 t's for .50 each--brand new, some glow in the dark, but all great for working in!
Jeans, overalls, rubber boots, aprons & gloves are the only other things I can think of.
Love your site AND that sewing machine--would love to learn how to sew!
