I had no idea about this; thanks for this information. Now I am sad about some 'artwork' my son has drawn that is laminated.I cannot help myself- please don't lament your child's artwork- I am sure it's good, LOL.
Lamination, yeah, that works for kind of short-term saving. After a few years though, the adhesive tends to separate and bubbles appear- plus, you can't remove it without ruining the picture. I recommend framing of anything you want to keep longterm. Spray the surface with a fixative first. I am guessing the laminated pics were done in class.
