Thank you so much for sharing this! I like to print your models onto ADHESIVE PHOTO PAPER and then "sandwich" the fold around cardstock paper (like cereal box cardboard). No glue, comes out very sturdy, and glossy photo paper is almost as resilient as lamination.
Thank you for something different but still an excellent watch. If I can post a little tip that might help some people, I have found that spraying the page after printing with a cheap hairspray (no need for expensive lacquers or varnish) really helps to set the colours. Of course you have to let this dry before continuing. As an alternative I have been playing around with laminating the finished minis to make them more rigid and last longer. As for basing, Peter Dennis, the great Osprey Books illustrator and producer of the excellent Paperboys range, uses a method of applying "Mod Podge" to card bases for his minis that works really well - use a fork to hold them upright while this dries.
Having backs is one of my largest deciding factors with choosing one mini over another. Okumarts miniatures stand above most of the market for this reason.
After making paper terrain for my miniatures for years, I finally decided to take the next step and start making paper miniatures as well. I'm in the white/no background camp, as I really like trimming the paper minis a little closer than you. I also use a scissors for most of the work, finding they are much better at curved lines than a blade. I do use a blade for cutouts (between the legs, for example). The important thing is that I find the whole process very enjoyable. I agree with your opinions on character backs, but I wonder if it has affected what kind of stance you can draw characters in (i.e. No foot forward). I also highly recommend the Litko bases. They are well worth the price. I do occasionally have issues with the paper mini slipping out of the base. I've thought about trying to put some post it like glue on the tab. Has anyone done anything else?
I might suggest a touch of Elmer's Spray Adhesive. It rubs right off. I would spray it on a piece of paper and then just tap it with the mini. It isn't really sticky, per se, just tacky and then it sort of helps hold the mini in. I haven't had to use it myself but I could see it as a helper. We also used to use rubber cement back in my graphic design days in the 80s. It's nice because it holds well and comes off the material easily.
I do the same thing as you, and I also laminate it. By laminating it, not only does it become more durable, but it also allows me to use non-permanent markers to mark initiatives, statuses, etc.
I like to purchase your models through DrivethruRPG. Do you have any plans to put out some "scatter" like terrain? Just stuff to fill out spaces? Crates, barrels, furniture, that kind of stuff.
