Scrap booking page kit

Ok, this may be obvious but I've never done it so... What do you mail 12x12" sheets in so they don't get folded?

I'm sorry. Also, what does it mean by: "one matching 42 to what ever is on the small gem adhesive page"? I've been scrap booking on my own for years. I don't follow trends or any specific company tho. I just pick up things I like weather they're made for scrap booking or not... This has me at a loss. I want to make sure I can find these things locally before I sign up.

Send them out in a plastic bubble mailer size 12".5 x18".25 They have them at walmart and also These little gems come in any color. They are self adhesive gems. The gems are on a sheet and can come with 42 gems or more on a sheet. I picked mine up at Walmart and there are 60 gems on the sheet I got yesterday. They are like crystal looking.

Thank you @biasbabe :-) now I feel dumb lol!

Don't feel that way @ABackwoodslife I just started getting stuff for my scrap book and I am just finding stuff myself that I have never seen before.

I was swinging on the 42 to also! Thanks for explaining!

You should have seen the Sale items at Micheal's yesterday in Erie Pa, all sorts of sticky charms etc and I picked up some beautiful Pad of Different Papers at Ollie's for $1.99. ( 172 sheets 6" x 6". TPC Studio). You never know what you'll find ! ! !

@BlueberryLady Isn't it fun to go find them Bargains! We have a Ollies and I never would have thought to look there. It needs to warm up a bit and less snow for me to get there. it is -1 here at the moment.
