Homestead Revival has a givaway going.  They are giving away Tatler reusable canning lids!  These lids are really neet, because they are reusable, the rubbers are reusable (up to a point), and they are BPA free.  The only drawback is that they are expensive.  But hey, if you can use them again and again, it might not be too bad.  I think that I will purchase some to try out this summer.  Maybe I could get a few each year, or ask for them for Christmas.
