First, removing the product from the packaging:
I don't know that I've ever had so much trouble getting a product out of the package before. I was hoping to keep the cardboard in relatively good condition, as there are lots of good tips on it, but no luck there. I was able to pull apart the paper in a few places to get the rings out, but I had to cut out the last few. Also be careful, as one set of stamps has instructions underneath them. They're basic instructions (the stuff they mentioned in the video with a few tips and example art pieces).
Onto the pieces themselves. As I was afraid, the rings are quite large BUT, if you put the stamps close to the tab on the stamping piece for the cogs and away from the tab on the gears when stamping on the inside of the gear, you can make pretty small designs, suitable for card crafting. If you're into scrapbooking, there's no problem and you can make quite nice larger designs with these, especially when using the outsides of the gears.
Here's a close-up of the circle cog, gear and stamper. The cogs and gears both have little arrows sticking out at the compass points helping you orient your pieces for symmetrical designs, as well as mini cut out arrows every second tab. This helps you if you're only stamping every second tab for more open (rather than overlapping) designs.
The tab system works great, though you have to watch the ovals, as not all designs will come out symmetrical (due to the size of the stamp and how ovals work.
And a close-up o the bottoms:
I tested the system with cling stamps that didn't come with it, to see if they worked. They do. I had no problem using other Inkadinkado cling stamps, as well as Local King Rubber, Fiskar's and Stampin' Kimmie. Alas, as the picture below shows, the system doesn't work with clear stamps. They're simply too thin, and don't clear the notch on the stamping piece and therefore will stamp if they're far enough away from the gear/cog, but not if they're close.
You can see what I mean in the heart picture below. The outline stamp is a cling stamp, but I tried to line it with a clear heart vine stamp and then add a clear solid heart inside. Neither of the clear stamps worked properly.
Here are some patterns I made, some with the stamps that come with the set, some with my own stamps. Tomorrow I'll post some cards I made using designs I tried on these 8 1/2 x 11 test pages.
