1. Find images that looks great vertical or horizontal.
2. Get pics with dominating color schemes. I used a blank wall at Starbucks because I liked the wood grain look.
3. Step back and take a wide angle shot. I use my iPhone because inspiration can sneak up and being prepared is a must.
Once you have them saved you can upload it to your cloud and use them whenever you feel like it. (I use a Time Capsule for most of my collections but have a few on my phone.)
For example I had a funny thought and opened up my A+ Signature app and within 5 minutes I created a Pin-able quote.
Below are a few examples of my own collection that I plan to use in the future :)
