Most people won't ever find a need for this BUT if you do- its good to know.
When I was teaching I had a toner cartridge that the copier wouldn't recognize for some reason but it still had quite a bit of ink left it. It wasn't until recently that I found out a way to get it out with one of the thousand syringes we have at our house. I attached it to the end of the ink reservoir, turned the ink down, and pulled the ink from the barrel with the suction of the syringe. I filled up an old jar full of this gel ink and I barely made a dent in the cartridge. So I have lots of ink to play with!
I even squeezed some onto an old ink pad and it works great as a distress edger. I can stamp with it but the images come out a little blurred.
NOTE: this is a resin based ink that is flammable and should be used in a well ventilated area. Avoid breathing in chemicals.
This is definitely my favorite tip that I use ALL THE TIME.
I'm a huge fan of those cheap but adorable wall sticker designs from Dollar Tree. I'm always on the lookout for the newest one because you can do several different layouts with one sheet.
I'm also a huge fan of using all the leftover sticker background to make my own stickers. If you've seen my quote journal pages, this is what I use for the words. I stamp out different words on the scraps for my own word stickers.
I also do this with the leftover clear sticker paper for when I print my printables. Clear sticker paper is more versatile because you can use the tiniest weird shaped pieces and you won't see the edges as much as you would white.
Sticker paper isn't cheap and there's no need to waste it when you can make your own stickers from the stamps you already own! Or make your own doodles.
