The thing about selling downloads is as a customer you get the product with in seconds or minutes after making the purchase. But I get there are some extra steps involved when buying digital downloads. You can also upload to various websites as opposed to goto nearest print shop. I think what I plan to do is offer both but offer the physical print as a empty order and when you order it you tell me what image you want printed. That way there is less confusion on what you are ordering.
Use Adobe Acrobat Pro (this is a part of Adobe’s Creative Cloud Subscription). Find “tools” on the top menu. Select “Forms”, then “Edit”, and “Add New Fields”. This will allow you to create editable fields for your customers built right into your digital products. Note: you cannot copy and paste your fields throughout the document to add more than one editable filed.  Instead, select “Create Multiple Copies” to speed up the process. You will also be able to give fields multiple lines and make them rich text enabled so customers can change the size and fonts of the text.

Another surprising video result:  Beth Anne found a tutorial video she created for her and Sarah's now-defunct Mommy blog on making cappuccinos at home with a frother.  That video has almost 5,000 views on it! Again, this video wasn't promoted in any way, it just sits on their Mommy blog which gets about 10-20 hits per day... so it's essentially dead.  The video is getting viewed because it's ranking for keyword phrases on Google and YouTube.
