Maybe you were thinking of Alexander Henry's Juicy Lemons? I think it's out of print, but maybe you could find it around?
RJR Fabrics makes a Farmer's Market line that is all pictures of fruits and vegetables. But, they are pretty realistic looking. Not sure if that is what you are looking for.
Lemons on black by Timeless Treasures
Robert Kaufman has a eco-friendly print that is pictures of leaves in a really pretty lemon color, but not actually lemons.
I am finally getting around to decorate my kitchen after living here a yr. I have decided on a green apple color to help brighten that space. I would LOVE to do a lemon/lime decor. I am looking for fabric online with lemons. I saw yrs ago a similar fabric but for the life of me I cant remember who makes it. I want a print that isnt cartoony but more like a drawing of a lemon kwim? I plan on sewing some valances and toppers for the windows. A few hand towels and depending on the print perhaps a few wall hangings of other fabric pieces.
