Soccerchick - Well, the way swaps were traditionally around here the swap was divided into 2 groups A & B. Each of those had the same elements. People signed up for one in group A. You weren't required to do group B - but if you chose to do both (and 98% seemed to do both) then you chose a different element but had to do the same theme.
Then too many people were missing out on the swaps so they started doing a whole new group of A & B - calling them things like Creativity, Innovation, Vision...stuff like that. Each of those had group A & B as well. Of course there were always people who signed up for Creativity & then looked at the themes in Innovation and decided they wanted those items as well...so they'd sign up for both. (Yes, I was one of the crazies! LOL)
So for my first swap I chose Princess squares in group A - then decided I was missing out on some really neat stuff in group B so I signed up for Princess borders. My stuff went together. I used the same cardstock for everything. For the squares I did heat embossing of princess stamps I'd gotten in a tub at Mikes: Cinderella, glass slipper, Snow White, mirror. For the borders, I used the same embossing powder to accent the computer font I used and for the star/pixie dust stamp from the same tub. Those were the things that were the same - there were other aspects to the borders as well.
I like when things work together - less I have to do when I finally scrap those pages
but am intimidated by the whole page kit thing.
It's hard enough to come up with a creative idea for a swap for a couple items. I put more into those elements than the things I do just for myself. If we don't do kits, you come up with an idea & just "copy" it to make the others. With kits, you have to come up with creative ideas that go together for ALL those elements.
So what I'm saying is there are good & bad aspects to both ways of doing it. Neither is better - just different...depending on your working style. And I'm good with whatever the group decides.
