Check out 5 star font site. Just saw an applique set that might be what you remember and thought you had.
Sue Box has some nice edges for use on doilies.

Have you looked in Embroidery Library? I know they have round ones, but am not sure about rectangular.
I digitised a lot of borders/frames, way back then but they were mostly squares, some split frames, etc. all different sizes, fancy and plain.
If it is just a 5x8 satin stitch frame you require please pm me with your emad and I will create one for you. I will need width of stitch required and format too please.

Try typing in machine embroidery rectangle frame. That might get you something close to what you are looking for.
There are several at Anne's...also Bargain Embroidery has lots with edgings and corners that you make the size you need...also lots of edgings and corners at Threads N Scissors....
Try golden needle lace doily designs or try applique lace doily designs. Hope this helps.
Go to Julias and select Mug Rug Club tab across the top. You can save the current design in two sizes, 4 x 4 and 5 x 7. If you don't want the Christmas tree design, insert your own design instead. It probably is about to change to the free January Mug Rug design.
Thank you I didn't know about these on julias site. They are not quite what I had in mind for this project as I am after only one layer of fabric like a doily but they may work if I can't find anything else
