What's something you own that you forget or struggle to use?

The Fuse tool. I haven’t even opened the package yet.

Sewing machine. I used to use it regularly with scrapbooking, but then we moved (lol, six years ago) and I never set it back up. I need to make myself use it again! I often want to, but I need to reacquaint myself with it.

When someone posted about the Heatwave being on a big sale at J's, I bought it and some transfer sheets... I was so excited, I put it in a drawer and have yet to use it. LOL! Maybe DD...

I have a LOT of stuff in here that would qualify...

Stamps. Own a ton. Hardly ever think of them when putting together a page unless I am lifting someone else's design.

Electronic cutterS. Yes. Two of them. My Cricut is sitting lazily on the shelf and has not been turned on for years. My Silhouette is in my sight lines, and I go to it when I can't find a paper or sticker or pre made diecut that will work for a particular project. And then I can't remember all its functions.

All the different foiling systems... My Minc gets a workout occasionally. Use the transfer paste for stenciling--and stamping when I think of it and remember how. My Foil Quill pens and metal mat get next to no action. And somewhere in the bottom of a drawer is a little WRMK hand held heat tool--the Fuse?--that was supposed to open the door to millions of foil creations. I like the look of foil. I just don't use any of these tools enough to get really proficient at using it And often don't think about it until other elements are already on the page or card.

Mixed media supplies. Lots of little pots and bottles and jars drying out on the shelf while I use the ones with which I am currently most familiar. Lately I have been using Oxides and VB art crayons. Occasionally I use paints. Love the look of pastes and glazes, but they don't get much play time around here.

wafer thin dies. i love buying them but forget to use them.

My mini Minc.

The "We R Memory Keepers circle spin and trim".
I love the size variety of circle frames it makes.

I struggle with it.
I've watched the tutorial videos and it hasn't helped me.
It not easy to use. Trial and error first, on a whole bunch of plain printer paper.
The circle cutter has to be used/done very slowly to ensure a complete and thorough acurate cut.

It's not something I use regularly. I have done three separate circle making days, and made a bunch.....and tossed a couple mistakes. 
Now I will only use it on paper that is on sale (4/$1--10/$2--etc...) or from a "3-4 sheets of each" paper pad. I will not use it on paper that was $1.00+ per sheet(learn from my mistakes!).

I would definately classify it as a "love/hate" kind of thing. I love final results. Hate the tedious process of making them.

Yes, embossing, and stencils too.

I should foil more - I didn't buy a minc, but I do have a laminator and bought some of the ready-to-foil papers. Foiling gives beautiful results and I'd love a hot foil machine for my gemini. But it feels like the supplies needed (plates, machine, variety of foils) is very very spendy compared to how often I would use it?

My Scan N Cut. I’ve yet to scan or cut. Don’t know what’s holding me back. If I can use my Silhouette, this shouldn’t be too much of a challenge.

I haven't used my embossing powders in a couple of years.

Mixed media supplies. I love playing with them on the rare occasion that I do, and I keep buying. But, it’s definitely an effort to drag them out.
