Although I haven't participated in as many challenges this year, the Caardvarks challenge site was always one of my favorites. They've posted their final challenge to create a monochromatic card. I needed an anniversary card at the end of the month and think this fits the bill:
Cardstock: Shimmer cardstock; Patterned Paper: Wisteria (Basic Grey); Heart punch (EK Success) and corner rounder (Creative Memories); Silk ribbon (Papertrey Ink)
