Slip Case and printing

Even though they're not in a book format I want to make a slipcase for my printed pictures

Here's a really, really rough test attempt I did, but I made a mistake with gluing the tabs so ended up with a messy little box

During this last week in which I have been printing my final designs, I've been running into a lot of problems with the etching process again:

A lot of my prints have been coming out faded (Aracknid the chauffeur had to be re-printed several times), or I've been making silly mistakes when putting them through the roller that results in them coming out misaligned/wonky. I've been working incredibly hard as well not to get ink smudges around the edges of my prints but this is difficult.
