Local quilt shop? Someone must be able to get you started! You can view those videos and tutorials - which are super-great on this board - but seeing it in person and having someone answer your questions, right then and there, is the best. Wish I was closer... but OH is a stretch. Good luck!
And my prayers for your grandmother and your family. Alzheimer's is not easy to get through, but know you are not alone, esp. if you educate yourself.
