I have a current fundraiser ongoing where I am trying to save up enough funds to build my Crafting Cottage to give me more space for crafting and creating videos for you. Here is more info on that https://youtu.be/IoI5JiJYmfM Any donations will go toward that cause. If you would like a chance to win a prize winning Blue Ribbon basket donate $20 or more.
