Endless Birthday Wishes is one of Stampin' Up's new polymer stamp sets. It sold out quickly but they just got a new shipment and it's available for purchase again. Yay! This set is SO versatile. Not only does it come with loads of words you can combine to make different sentiments but it's polymer which means it's flexible enough to bend into shapes like I did on this card.
The half pompom is made by tying several loops of thick baker's twine together, snipping the ends and unraveling them.
