Pen display making during thunderstorms in NC

I have been thinking of ways I could display pens for really cheap. I got this old poster frame for free. I just turned the poster around and put the metal clips in the front instead of behind it to give it a shadow box look. 

Next I went through some supplies thinking how can I fix pens to a picture frame. I found a couple of rolls of hook and loop tape from Harbor Freight. Right now the rolls are on sale for $6.99 and offer 35 feet per roll. It took a bit more than one roll for this huge frame. I recall the measurement across the bottom is 30 inches.
I laid some pens on the board and decided how I wanted them arranged so I could easily see the colors and choose or service the pens. I made measurements to estimate how much supplies I would need and make sure I would have enough.
I started with one row of pens and tested it out to see how I would like it and how many rows I think I could make.
At first I used Elmer's glue but it didn't hold well. So I tried Tacky glue. It worked but I tried Duco glue at the same time. It also worked as well and seemed to dry clear and not be as messy as the Tacky glue. I went with the Duco glue since I had more on-hand also. It took almost a tube of Duco glue (~5 buck at Walmart).
I rolled out the rough side of the hook and loop to bond to the board. I just thought rough surfaces bond better than smooth. Sort of dumb really because the other side is the softer velvety side of the hook and loop. I think it might have absorbed more glue. Plus the board is styrofoam inside and solvent glue could melt styrofoam. I tested the glues in an area where it would not be visible to make sure it wouldn't melt my board.
After I got the first strip of hook and loop, I started digging in my pens and sorting out what still works and what is a good pen worth keeping. I laid them down and rolled the opposite side of the hook and loop over each pen, pressing about one finger space between each one. This forms a nice stiff little loop that can expand or be pinched down to accommodate a smaller diameter pen. So it is slightly adjustable for different sized pens. I made sure to get the loop tight enough the cap or some part of the pen would prevent it from falling out. I hung it up and waited over night to make sure nothing came loose or fell down. It worked. I can now see a whole range of art supplies at once. Maybe eventually I can fill it with pretty fountain pens.
One pen is missing because I am already using it. It's my grail pen of course, a Noodler's Safety pen. I think I did this project for under 20 dollars and I enjoyed it. I think I need to stop buying pens too.
