I just found this challenge & it looks like a lot of fun. I figure it could last me all summer - ha-ha! This is Gracie. I used her because she had lots of space for the pattern overlay. I liked this net background for it's great lines - they seem to draw the eye to Gracie. I used a plain linear frame because the original had frosting swoops & I didn't think they quite fit the theme.
SG_ANarrative_Emb_BHA_FloralBurst, KME_PieceOfCake_Paper_Icing and a simple sans font, I think it was Gil. I usually like a fancier one, but it fit the linear theme here.
Oh, yes, I used GIMP.
