I have been working on a project that involves gluing two sheets of cardstock together, then laminating the result with clear contact paper. It's a bit of work, but seemed more reasonable than purchasing a $200 laminating machine.
Maybe not. I had been pleased with the results, but noticed that the rubber cement seal was coming apart in some places. No problem, I thought, I'll just slip in a little extra rubber cement. That appeared to be a fine solution, until I returned to my work an hour later and discovered that the solvent from the rubber cement had apparently penetrated the card stock and dissolved the adhesive on the contact paper, leaving a mess of wrinkles and bubbles. :(
Time to figure out Plan B.
I've also been looking at laminating machines....
If you continue to notice problems, ie, after a few days, even the dried rubber cement is adversley affecting the lamination, please let me know. I was about to go out and buy both rubber cement and contact paper.
I hope you'll find lots of other uses for a laminating machine if you get one. If you get one, you might not have to do the second piece of card stock.
Panic is not, in general, a good thing. Patience almost always is. When attempting to redeem a disasterous situation, if you find your efforts doing harm rather than good, stop. Go away, leave the project, do something else. (Easy to do when you've seen your work disintegrate before your eyes; that rather saps one's inspiration.) Sometimes, a little time passing can make things look better. And sometimes that's literally true! After several hours, the horrible bubbles and wrinkles have started to subside (on their own—the places where I tried to interfere look worse) to the point where I believe the work is salvageable! Not as pretty as I would like, but it gives me the courage to keep going.
A laminator is still attractive, but I'm not going to wait till I decide to buy one to get on with the job!
