Size. I usually start with 4x6 or 3.5x5 photos and make standard size (4.25 x 5.5) cards. This dimension usually requires cropping the 4x6 photo, so I will sometimes make larger (5x7) cards if I have a 4x6 photo that I don’t want to crop.
Types of photos. I have found that photos or architectural elements (doors, windows, flower boxes, statues, etc.), landscapes, flowers, and interesting street scenes all lend themselves well to photo cards.
Construction. I like to mat the photo with a thin mat on solid cardstock and then use patterned paper for the card itself.
Greetings and Sentiments.
1. When looking at photos, some have images which fill the entire frame, while others have a lot of negative space (open sky or a plain wall). Those with negative space are naturals for allowing you to add a greeting, quote or sentiment. Notice that “negative space” does not have to be completely empty space - it can be grass or meaningless foliage. In the cards on top of this post, a house in the background and a wall served as the "negative space."
2. Sentiments can be stamped directly onto photos using stayz-on ink or can be stamped onto vellum, cardstock or tags and then placed onto the photo/card with vellum tape, adhesive, brads, eyelets, etc.
3. I find that photo cards work particularly well for sympathy, thinking of you, just saying hi and birthdays. I used up a bunch of "extra" pumpkin patch pictures one year to make birthday cards for fall birthdays, for instance.
4. Consider witty, funny or ironic greetings as well. This is a terrific opportunity to use all those quote stamps you just had to buy! Remember this photo:
I've been considering all kinds of greetings to use with it. It could be something funny like, "What if the hokey pokey really is what it's all about?" or "I hate it when that happens." (yes, I have stamps with those sayings). Or it could be something along the lines of "Missing you." Which do you think would be better?
4. Blank cards (without a sentiment) work well with very strong photos or those which have a strong sentiment inside. I have used the flower photo above as a blank card (without a sentiment) many times.
Final Assignment: Look at this photo and come up with an appropriate greeting (either inside or outside). Bonus point if you actually have a stamp with that saying. Double bonus points if you can make it something Valentine-related. Go!
