Use them!

One of the best things with swaps - seeing techniques as well as having pieces ready to use. I seldom do pages without at least one swap on them.
Only exceptions - Charger plate is home decor, so it is on the shelf. Chunky Charms - one is hanging on my scrap bag. I only have two others and they hang in my scrap area and are just pretty to look at.
The rest of the swaps? Two locations - either by paper line or there are several boxes that fit in my shelf and I keep swaps sorted by type. Most are shoebox size. The boxes just make it quicker for me to locate swaps I want.
Without looking, the categories I use/remember:
Page kits - then a few folders/bags sorted by Heritage, Birthday (three bags - masculine, feminine, general), Outdoor, Other
Animals
Journal items
Flowers (except rosettes - they have their own box)
Kitchen/food
Characters
Outdoor
There are more as one box has things filed in labelled baggies, but I can't remember at the moment. I tend to go through them when I get ready to scrap to find embellishments. One of the boards I do stuff on has monthly challenges where you are to use swaps for something. After doing those a few times, it helps you get into the groove of using them.
The paper line pieces are kept with that particular paper line. I received this large floor to ceiling unit with 18" square trays that someone was about to toss! A bit of cleaning and I keep my favorite paper lines in most of the trays. Exception - bottom 9 trays keep scraps, sorted by color.
Over on my blog, there is a kit I just posted for a challenge - if you scroll down towards the bottom of the post it shows the swap items I plan to use for the particular project. I may add more at the end, but these are the basic ones. (If I get this to work, the photo is below, otherwise, my blog is

Seems a long way to go to say - I use them.
