I'm sorry I missed the creation of the cupcake toppers, but hopefully this will help someone in the future! You can use your Cricut and printer and get nearly perfect alignment with your printed/cut out images. First, you need a graphics program like Inkscape or (what I use) Adobe Illustrator.
First, create your image with graphics and cutting outline in your design program. I'm pretty sure Inkscape works similarly to Illustrator, and it's free. So, here's a graphic - apples, set up on your page the way you want them to print out:
You can't see in the top picture, but I've already traced around the apples, the way I want them to cut out, like this:
So this page has two layers in your graphics program, one with black outlines, one with the colored apples.
Now, open your apple image in your Inkscape/Illustrator, toggle the colored portion of the design 'off' so that only the black outline is visible, and print it out FROM THE GRAPHICS PROGRAM on your home printer. Now you have a template. Take the same black and white tracing image, save it in SVG format, open it in SCAL, and cut your apple shapes out of plain white paper. At this point, there won't be any color on anything.
Now, take your printed out sheet with black apple outlines, and a repositionable double sided tape runner - I use Tombo - and use that to attach the blank white cut out apple shapes, perfectly within the outlines you have printed on the page. Tip #1 - make certain you run the tape along the top, or leading edge of EACH image - the top of each image will feed into the printer first and this will keep the paper from 'catching' or peeling up and causing a paper jam or messing up your printing. Tip #2 - similarly to the way some people press their hands all over a brand new, a little too sticky Cricut Mat, you're going to press your hands down a few times on the double sided tape to 'destickify' it - this will keep your cut outs from ripping when you pull them up.
After you have your cut outs all taped in place, you're going to go back to your graphics program, toggle the black outline 'off' and toggle the apple images 'on'. Now, you're going to print out the apple images, again FROM THE GRAPHICS PROGRAM. The images should align perfectly - and should print out exactly in alignment on your cut out images.
This whole procedure sounds ridiculously complicated, but after you've done it once or twice, it really only takes about 2 minutes to set up each sheet of multiples you're printing out - which is nothing compared to the time you'd spend cutting these out by hand!
Also, I've never had any problem with paper jams or messed up printing - I'm guessing that's determined by how well you attach those blank images to your base sheet, and what type of printer you have.
GOOD LUCK!!
I'm very tempted to pick one up for all the print & cut projects I have swirling around in my head. There's a lot of beautiful & amazing papercraft projects out there on the Internet, but many of them are print & cut - and I'm too lazy to cut by hand
