I was asked where the best place is to get classes on the Cricut. My favorite place is Personal Scrapbook in Allen. Not only do they have classes but also crops dedicated to Cricut users. I have not been to their newest storefront but I understand that it has lots of room. They also keep a great selection of scrapbooking and crafting products.
In Plano there is Stamp Asylum. I cannot speak about their classes or crops since I have never been to one but I see how many they host and am impressed just on content. The store is amazing in it's variety alone and the staff is always helpful.
In McKinney there is Scrappin' Bunnies. I have only shopped there twice but love the variety and prices. I know they have monthly classes on the Cricut.
hope this helps
