That's why I don't care for some sketches because they are WAY too specific for me by showing photo placement, photo size, etc. I think that can limit your creativity. KWIM? I know my sketches are VERY general, and my team creates AMAZING and such different things from each sketch. My sketches are a jumping off point to get you started and really creating instead of copying specifics. I encourage people to flip the sketch anyway, create a layout, card, tag, altered art with it, anything! Sketches can be helpful but they can be a hinderance too IMO.
As someone suggested, put them away for a while!
Just enjoy crafting and creating!
