What are/were your (papercrafting) favorites for 2023?

Yikes! That's a big list PaperAngel. And a Happy New Year to you also. To everyone.
I can't answer in all of those categories but will do a shortened list:

Product - Thanks to you guys , I guess my product will have to be Stencil Butter. I purchased several jars this past year; so pretty.
Paper Collection - Can't pick just one but I did like several Simple Stories lines as well as some Carta Bella.
Ink Brand - 2023 also saw me get on the Distress Oxide bandwagon. So many colors!
Stencil Pattern - I'm also new to stencils but one of my favorites so far is a Crafter's Workshop chicken wire.
Technique - Falling in love with paper tearing again.
Storage - I just ordered some inkpad storage fr sb.com that I hope will be the answer to corralling the D.O.inks that I bought this past year.

Paper collection - Too many to list. I'm a huge fan of 49 & Market, though - particularly the fall line and the ocean one. Also, a few of the Simple Stories lines last year were really good- I liked the vintage one and the harvest one.

Embellishment - Filmstrips. I love all of my layouts using filmstrips. I've also become a fan of frames and I never used them until last year.

Tool - My wax pen thing that manicurists use. So great for picking up sequins and other fiddly things and getting them in the right place. I love it.

Stencil pattern - I used a lot of grunge type stencils this year. One of my favorites is the coffee cup ring ones. I used dots and leaves a lot, too.

Adhesive - Still love my Scotch double-sided tape. I know people frown on it but I've never found a scrapbook one I like as much.

Layout design - I'm trying to break myself of the habit but I put one vertical piece to the left and then a horizontal piece crossing it towards the top and then my photo where it crosses, a little bit to the left. I use it way too much. It always looks good but I need to branch out more.

Inspiration - I follow a lot of the designers for NJFB Kit Club on Instagram. I like the style a lot of them use. And of course, the quarterly sharing thread here.

Purchase - I finally bought a Cricut. I haven't used it as much as I should. I'm going to try to use it a lot more this year.

Storage solution - I wish. Hoping to get that in control this year.

I'll add a few:
Kit Club - NJFB hands down. I tried 3 others this year and I still love my NJFB's best.

Etsy Store - Shadnee. I love my wood and acrylic pieces.

Online Scrapbook Store - A Cherry On Top. I like their sales, picking cherries, and that they listen to us and answer our questions on 2peas

My favorite collection of 2023 was 49 & Market Vintage Artistry Moonlit Garden.
I guess my favorite brand for 2023 was Bella Blvd since I bought more from that manufacturer than any other in 2023.
My favorite adhesive has always been Scotch double sided tape.
