I love this background stamp by Hero Arts. I've used it on two other posts: Best Wishes and Friend and I'll have another won to share coming up in the next few months.
For my card I stamped the background with Versa Mark ink and heat embossed with white embossing powder on watercolor cardstock by Strathmore. I colored the images in with Peerless watercolors and a water pen by Ranger. The sentiment is vellum by Quick Quotes. I die cut the vellum with a Spellbinders die before I ran it through my Xyron sticker maker to adhere to the card front.
Very simple but anything more would make it look cluttered. I will say it took a while to color in that background, which made me not want to do anything more to it.
Thanks for coming by and checking out my new card.
