hello! sorry i lost track of this forum so i didn't see everyone's posts! thank you everyone for the compliments, i'm just glad to help out
i really wanted to figure it out, so when i finally did i wanted to share with everyone else too!
funtodecorate2 & butterfly831915: as Katherinej51679 said, i think the billows may be too heavy to be placed straight on a buttercream cake, i'm not entirely sure though
let me know if ya'll try it out please!
cakegrandma: the squares are 2"x2". like MadMillie said, the directions are posted as the caption to each picture so you have to enlarge each one to read it
funtodecorate2: i'm not sure why they aren't getting puffy! are you using gumpaste? maybe you're rolling it too thin. i found that if i rolled the gp too thin it would scrunch up and look kinda funny, so maybe just play with the thickness of your gp. also, another little trick would be too make the billow then push your finger through the opening in the back to fluff up the center. if the center keeps falling in or scrunching up, the gp may be too soft. i hope something i've said helps some! if not, i'll keep watching this forum to hear back
