Dear Moyed, this FSL supports extra stiches on it. The design I uploaded to Design by Cuties, comes in blank, so you can add your own lettering. I hope this will work for you. :)
Love,
Yoriko
That is a good question because some of them are not dense enough for words or designs.
I found what your are referring to, the heart specially designed for Meg and Ray. As it is Yoriko's design you can be assured you can put your own lettering in without any trouble. She is a great digitiser and her FSL designs all stitch out beautifully.
Will you find the design and post the link for us, it is very time consuming to find it, with the info you gave TY
What about clicking on that person name in the left top hand corner and emailing them with that question.

Maybe you could give a link or post a picture so we could see it.
