I made these fun, vintage "poison" bottles to scatter around the house.
They look really cute in bathrooms or in kitchens.
Finding vintage labels can be tricky, but I found an awesome website called Graphics Fairy they have the coolest vintage clip art. She has a really reasonable copyright use agreement, but please read and respect her wishes. Look under Halloween, bugs, and anatomy to find some interesting ones. There are also a couple of websites that you can download old typewriter fonts try Font River where you can type and print words like "Poison" or "Dragon's Liver" etc. Picmonkey is also a great site for all sorts of fun Halloween graphics.
