as they become available with no additional charge. They are free, one at a time, at Stitchery Mall, but if you miss one... they can be expensive to buy individually. The price on her site will go up as time goes on and more letters are available, but you will get the same thing. Also, if you purchase the alphabet, your purchase is registered and you can download any missing or lost letters at any time. If you only miss one letter you will come out about even. Sounds too good to be true, so I asked her to be sure. Once in a while, something that sounds too good to be true really is true. Love, Lois
