Pic of my first cookie I decorated and is my favorite

I’m about to start culinary and pastry school i know it’s not needed but the va is paying for me to go and I love cooking and baking. My flavors are there but my decorating definitely needs work. My neighbors are offering to pay for my cookies and I’m only charging for ingredients as it will help me practice and I’m not wasting food. Anyway I want to eventually open an in home bakery when I get really good and I want to know where you get the perfect sized cookie cutters? I feel like mine are on the smaller side but they are from hobby lobby ????
