Here's my before/after project:
The heart is needle felted (poking it with a special needle at least a thousand times) Yeah, piercing the heart... yikes... lol...
The balls are wet felted... I would needle felt it a little until it resembles a ball, then dunk it in soapy hot water, roll in my palms until it is small and tight. Air dry, then thread it onto the heart. It was surprisingly easy. I did make few mistakes with wet felting because I didn't realize I had to needle felt it into a ball first.
This heart is now found on my etsy shop. And I do accept custom orders. Christmas is coming!
Have a great Thanksgiving!
