I found some free ones on the next links. You have to sign up to download from landof1000stitches
Which ones are you talking about? There is the Cute Alphabet one and then there are the ones here on Cute Embroidery. Also some in Designs By Cuties on this site.
For the ones here go to Home at the top of the page, and then you will see the free letter of the day. Or you could click on Alphabets at the top of the page.
