Simply apply adhesive magnetic tape across the refill pages and add the nested dies. Depending on the shape you may choose to orient the tape vertically instead of horizontally. Almost all sets fit two per side. Below you can see the two petite ovals on page, and the Labels One and Star set on the other. You may choose to have all your square sets on one page, with the Large and Small classic sets on one side of the page, and the scalloped sets on the back as I did (in case I need to pull that one page out to do a project I have them all, OR to have them on pages facing each other so you can see all for sets at a glance, I like that idea, too. (The nice thing about these is they are easy to change around if I decided I want that set in a different spot based on how much I use it or whatever, just pull them off one magnetic strip and place them on another, it's all the same!
There are only a few exceptions to this: scalloped sets in a few cases overlap when they are nested together which makes it hard for them to have enough contact with the magnetic tape to grab on because they are sitting on another die.(I have only had this prblem with the squares and hearts, so not all sets overlap)) My solution was to go ahead and use two side of the sheets so I could split up the sets and have room in between each, I don't really mind that they aren't with their "partners" LOL! So what you see here is just two sets of scalloped squares, broken into four groups. It actually makes it a little easier to see the difference between the sizes and to pull of the one you need without upsetting the rest of the set, KWIM?
The other exception is the long rectangle sets (there may be others, there are a few fancier long die sets I don't have) there is no way to put more than one set of these on a side, not diagonally, side to side, above or below, believe me, I tried! ;) I found I also needed to have more than one strip of magnetic tape to hold them as there was such a huge difference in size, the longest ones need something to grab near the top and bottom edge so I used three, the smaller ones are fine to just have the one going through the middle the way the other sets do.
You may want to reinforce the other sets with more strips as well. One thing I will mention about this system that has both plus and minuses: The pages are very slick, the positives are that the magnetic tape is repositionable if you need to move it, AND if you decide you want to use that sheet to store stamps again instead you take the tape off, NO residue! i love that it's not going to ruin my pages, yeah! The downside is that if you don't replace you dies and close the binder up, the magnetic strip is going to want to grab onto the magnetic strip and dies across from it on the opposite page, KWIM? (but will still be stuck there when you open, you just pull it away and stick back onto the other page.) It can't though if you have the full set on there,(and you need to put your dies back anyway) the other alternative is to only use one side of a page for your dies so they aren't attracting each other.
The binders hold 6 sheets, if you use both sides of every page. Doing so, you can hold 24 sets in this one binder that takes up 1.25" wide of counter space (9.5" high and 7" deep) I LOVE that! I chose to put them in an order than makes sense to me all the classic geometric shapes first, followed by the fancier ones and tags, these last in the order I use them most, so I know where to flip for the set I need (when I was using my CD cases I didn't always put them back in the same spot and would have to scan through the spine labels to find the one I wanted.) However I'm thinking i might use my SU! Round Tab punch to create some tabs for the tops of the pages labelling each for an additional reference, there is room on the top of the pages to do so...what do you think?
