Have you ever had red berry wreath, picks, sprays etc, that are made of foam berries? If you have, I'm sure you have experienced berries being stuck together by the paints or glues or sometimes just a berry will be damaged....and it shows!
Don't fret! You can either snip off the damaged berry, or just leave it in place and touch it up with a red permanent marker. Sometimes the finished berry product is sprayed with a protective coating to give it more outdoor endurance and this can lead to smaller berries clumping together. It's best not to try to separate each little branch individually, just separate any of the larger branches. When you pull branches apart, there is bound to be some of the red surface pulled off a berry here and there. Touching up with a marker is the easy fix.
