So I went online, did a google search and found a picture of opals from the website All About Opals (oddly enough!), and I printed it on some Whisper White cardstock. I chose Tempting Turquoise and Brushed Silver as complementary colours to the photo.
For the cover, I stamped "Opals" with Lovely Letters and embossed it in silver on some vellum paper, then attached it over the image with silver eyelets. I matted this on turquoise and adhered the whole thing to the silver cover. For the edge, I put in more silver eyelets and threaded Whisper White taffeta ribbon and silver elastic cord through it.
And voila! I hope mom likes it!
Blessings to you,
