Welcome! I'm in Sacramento for the weekend, but I uploaded my pictures right before I left so I could post from here. There are different ways to make shaker cards, but this is the way that I use. It has the advantage of being able to work on a circle instead of just straight edges. This was the PTI Tag-Its #9 card that I had posted yesterday, stepped out below.
Here you see both my frame and my stamped base, cut the same size with a 1-3/4" circle punch. Although you cannot see it, the clear window is already attached to the frame layer, right next to the underneath-side of the frame piece on the left. The slightly tricky part is the foam tape layer. Keep in mind that while I used one layer of foam tape here, you might have to use either thicker tape or double layers, depending upon the thickness of your shaker material.
Have you ever sewn a sleeve into a garment? Did you have to clip the curve? Here I have I clipped the curve in my foam tape. After I have cut the tape to the width that I want it (in this case, about 3/16"), I clip just part of the way through that width so that the tape is still in one piece on the inside of the circle, and it has gaps on the outside of the circle to allow it to follow the curve of the shape. Make sense? This clipping is what makes the tape work around a circle. It's a simple step, but an important one.
Next you carefully place your beads, faux snow, or other material inside your frame piece. (Remember that it already has its window in the frame piece.) I generally avoid using a fine glitter, because I have had problems with it clinging to the window sheet/acetate with static electricity. In the picture above, I have too many glass microbeads in there. I dumped a few out before taping up the shaker, and I should have probably dumped just a few more out than I did.
Gently peel the backer layer off of your foam tape. Since it was not cut all the way through (clipped the curves), I could pull it all off in three or four pieces--not thirty-something pieces. Next you oh-so-carefully pick up your focal image and lay it precisely where you want it, upside down onto the tape. You pretty much get one shot at this, so you need to make sure it is where you want it before pressing down. **If you cut your focal image layer slightly smaller in diameter than your frame layer, you don't have to be quite as precise in placing the layers together.**
I added a mat layer behind my shaker and mounted it to my card front--it's pretty simple, really. You just have to be careful at a couple of places along the way. I hope that helps; thank you for stopping by today!
