I have this cart for my Cricut and I kept fighting with it. I'd look up instructions and get something to almost turn out, but I wasn't ever really happy.
I have had an epiphany! The flowers are put onto the cartridge display in pieces sorted into columns. If you start at the top of the column, you will have the center of the flower. Then, you simply cut each pattern down the column and you will have the middle and outer petals of the flower. Last, at the bottom of the column, you have leaves that match the flower.
For an initial test, cut everything at the same size. 2.75" is a good start. after you play with your flowers a bit, you'll find which pieces you want to cut smaller or larger. I like to cut the centers up to two times larger because I like they way they look.
To roll up the center of the flower, start at the outside of the spiral. Roll around a toothpick or needle to start. I use a paper piercer, because it has a nice handle on it. I don't roll around the paper piercer for long, only an inch or two. I remove it and keep rolling. The ruffled edge can do whatever it wants, but the goal is to keep the smooth edge even, to create a flat piece that will glue down to the tab that's left at the end. The angle of the spiral will cause the petals to fan themselves out. Then allow the spiral to spin loose to be just a smidge larger than the center tab. Don't worry that you aren't gluing down the entire spiral. It won't came apart if you glue enough of the first length that you rolled up to create the center.
Once the glue has dried, I bend the petals out with my fingers, one petal at a time. If I try to do too many or bend too far, they will rip or crush and the center of my flower looks a bit worse for the wear. I've found that warm, barely damp fingers also help. Cheap paper is frustrating to work with.
It is dark in my studio at the moment and a picture will be a fail. When I have sun, I'll add photos.
