Some of our samples began with gesso, others with gel medium. Do you have supplies that you bought for a specific project but never learned how else to use them or how one product differs from another? This class was extremely helpful.
Some of my samples were completed in class and some were finished at home with additional or different touches due to availability of what I had at home. I didn't think I would like the image transfer (the raspberry photo) but the more I look at it (especially in person), the more I think I might use this procedure again.
The above photo was taken indoors on a cloudy day. The gold looks dark and rather flat in color. The rhinestones and other dimensionals don't really show the spritzes of gold, pearl and pink that I lightly layered over areas.
The two photos below were taken outside and the shimmer is now visible.
(here) which I really enjoyed.
Don't fall into the rut I was in. Experiment with what you already own and use some of your least favorite embellishments and papers. If your experiment works, hooray! If you hate it, you're not out anything but some time since you weren't using those supplies anyway, at least not in all the ways they might be applied.
