I have just finished reading a post from last year, 6 pages long, on this very subject. I was going to revive it, but I thought others may not want to read all 6 pages. So, I decided to create a new, fresh thread for more recent items that people wish they hadn't bought!
Most everyone on that thread agreed that they don't like stickers, at least the older style that are flat with the white border around them. They also agreed to the tons of eyelets and brads they bought, but me personally, I like brads and eyelets and use them quite often. Then there were the deco scissors, but I don't feel so bad about mine because I bought them 10 years ago, so it's no recent waste of money, and when I bought them, they were the "in" thing and I used them a lot (regrettably, lol)
I wish I had never bought the Making Memories Tag Maker, you can't see inside the machine, so the paper falls out of the metal rim, then you squeeze and half the rim is crushed, the other half nothing...just a waste.
I also bought a circle/border edge punch. I bought it a couple of months ago and I haven't used it, and I don't see myself using it. It was only $6 though, so not too bad a waste.
Then there are the 2000(?) piece scrapbook kits off of the QVC or HSN shows. I maybe use 1/3 of it, the rest I have given away or hold onto waiting to use.
So, of all the new products that have come out in the last couple of years...what do you regret buying?
