Hi Charleen, good to see you and Charlie here!!
Trish, leaf castings are much harder than this. I'm a visual learner too. But sometimes it helps when you just make things up as you go....then nobody knows if you goofed up but you!
Becky, you can pretty much form QW around anything. On the styrofoam balls you really have to mush it into the styrofoam though to get it to stick initially. Since a styro and/or plastic cup are smooth, I would cover them with the self-adhesive drywall tape first. Otherwise the QW will probably slide right off.
I think even if I retired from work and played full time I'd never get all the projects done that I'd like to!
