I feel the same way as you having strangers in my home, so I don't do open house shows. But I do house parties, and I love them. Usually most of the people know everyone there so it's a lot of fun. They come to buy, so you always make good money. I'd rather do house parties than anything else, but I won't do an open house at my home. I'd rather think of myself as being safe, not paranoid. These days you just never know. Better safe than sorry, any day of the year. Good luck on whatever you decide to do. And yes, get your money up front for any order you take. At my house parties I usually take what I have in stock, and I try to make sure I have enough, but I'll always take orders. I do find people really like to take their goodies home with them the same night though.
