I have looked all over the Internet to figure out how to pin from my phone. I took information from 3 different websites to figure it out. Here are the step by step directions. My phone is an Android-based (Ice Cream Sandwich) Samsung Galaxy S3 but I think it would work the same way with all Android phones.
The first thing to do is download the Pinterest app from the Google Play store.
Install Pinterest to your phone.
After it is installed, using the web browser go to the website that you want to pin.
You now want to go to "Share Page" on the Android. The way to do it on the Galaxy S3 is to touch the icon in the lower left bottom corner. There should be a selection to "Share Page." (Sorry about the glare.)
Touch "Share Page" and another window will pop up with the pinnable images on the website.
Touch the image that you want to pin and another window will open. Touch "Create Pin."
Your Pinterest account should open. If not, you will have to login to your account. Select the proper board and touch "Pin It."
On the Galaxy S3, watch at the top of the screen. It will say "Pinning" and then "Pinning Successful." Here it is pinned on my board. See the far upper left corner.
I am an AVID Pinterest pinner so I had to have access to pinning on my phone. Now when I am waiting in line somewhere or riding in the car ( NOT driving, of course), I can spend my time PINNING!
There is a link on my blog to follow me on Pinterest. Happy Kwilting and Pinning!
