Yes, you CAN use flowers and pearls for boy layouts. Especially when you use them in neutral colors. I used both in neutral colors to match the neutral Fusion collection for this layout:
The mini alphas, glitter alphas, flower and pearl are all from the Fundamentals lines. While I was pulling out some Fundamentals for my layout I notiuced soime fun black tags and started adding other elements to them to see which stood out and looked the best.
I used a layered sticker from a wedding collection, some paper twine from the Nostalgia collection and some gems and a flower from the Fundamentals collection. Even though I am not sure what I am going to use them for yet (cards? layouts? gift tags?) I had fun making them and seeing all the fun RRBF goodies on the simple tags. Do you ever pre-make tags and keep them in your stash for future projects?
