I use Paper Binder Clips. They come in a variety of sizes and are multi-purpose.

and here's 130 120 various sizes for under $8 USD

Something like this is intended for use with miniatures, so it'll be similar to the kinds you'd buy once you have minis...

But I would recommend making standees like these. All you need is binder clips and paper. No glue, they just naturally clamp closed around paper. Couldn't be simpler. Printer and scissors. I personally prefer them to minis.

You gotta clamp it down to the bed, or it'll move during printing. I use the smallest of binder clips on the corners and it works great.

Also, I've tried most of the adhesion solutions out there and I've had the best luck with hairspray as an adhesive. Specifically Aqua Net hairspray. Or if you can't find that, some kind of super duper ultra level 10 Hold hairspray. I print PLA, PETG, and even polycarbonate and it works great. I get a nice, flat glossy finish on the bed side of the print.

Yes, the glass is super conductive to heat and I use the same heat temps that I would use if I printed straight to the bed. As a matter of fact I rarely go above 50C on any of the filaments I mentioned above with success. I credit the glass to distribute the heat more evenly across the surface compared to the hot spots /cool spots you'll get with the aluminum bed alone.

Now, one caveat of using glass is that you're adding more weight to the bed and at higher print speeds and with the Y axis jerking back and forth, you'll see imperfections in your print of you don't have the printer's frame good and tight. I don't have all those cool frame upgrades on mine like a lot of folks do because I aim more for finish quality than speed, so I rarely get above 65mm/s on any print on the Anet.
I have a larger CoreXY that I built that I can get up above 100mm/s with good results but I rarely run it that high either. My benefits from it are larger build area.

The only improvements I've made to the A8 aside from a better power supply and Mosfet for the heat bed for safety, is the glass bed, a Bowden extruder, belt tensioners and these little guys :

Those base clamps produced the biggest improvement in my prints of anything I've done.(As far as frame stability is concerned)
I bought a cheap Ikea table and screwed the A8 down to it and now the whole thing is rock solid.
I get really nice stuff from my little A8 and I've had it 3 years now. I bought it when you could only get them from China, before they were available on Amazon.

If I had it to do over again the only thing i would change is probably the Bowden system. It's a bit of overkill for my needs since I'm not looking for more speed. But it is easier to load filament into than the stock extruder.

Please know these things I've suggested have helped me, but your mileage may vary depending on your printing needs. There are tons of opinions of what is best and what is not as far as upgrades.
