I love daylilies and my yard, which is covered in them, proves it. These flowers, which are from my yard, were photographed and extracted by me and saved in PNG format at 300 dpi. Shadows were added for preview purposes only.
These flowers are ok for commercial use, but would be perfect for your personal stash as well (just imagine the great clusters you could make with these). They are also S4H and S40 friendly.
No credit required for the use of these items, but it's definitely appreciated. Elements can be used as-is in your scrapbooking kits, but need to be modified for use in freebies.
