My FI is printing them on a color laserjet at work, but you can get them done at a Kinkos or similar type of printing place. I printed out 2 copies on my home computer so I could practice, and definitely takes a bit of ink!
I saved mine as PDFs after I was done, and just made sure to uncheck "Fit to Page" on my printer options (it distorts the size - was worse when I was trying to print chapstick labels!).
I'm planning on writing an instruction sheet to my FI on what goes on what paper, and what is doublesided. I would suggest doing the same thing at a Kinkos, and seeing if they'll print out 1 for you first so you can check it. They probably do things like this a lot
I gave the 2 I printed to FI's parents & sister (who are staying with us this week) and they LOVE them. I'm so happy
For the template, I downloaded it in Word to my computer and customized it. It was kind of a pain, not going to lie! I'm not sure I followed the instructions...but I figured it out Once I had it how I wanted it, I saved it as a PDF and test printed it in B&W (to make sure it looked good).
My suggestion is to search google for transparent background images, unless you're planning on printing on white background pages. You can search to see how to removed a background, but that seemed complicated to me lol
