I just got finished making a custom Instagram icon / button for use on your websites! I also have the .PSD files available for download if you would like to tweak it or perhaps just give me some feedback! I am still new to photoshop, but I am trying out button creation and photo editing for kicks. If you do decide to download it, please give me feedback through my contact page and share with me what site you implemented it! I know there aren't that many custom Instagram buttons available, so I decided to give it a try ;)
Thanks all! I will be making more and tweaking this one throughout the day!
