Let it be known that I suck at tape manicures. They are not my bag. For some people it's watermarbling, others can't stamp. I can't get to grips with tape. I just don't have the patience or the co-ordination - something which you need for tape to work! So I went for something simple and fairly difficult to mess up and it came out ok (this was my second attempt mind...)
I went for a black base, lay down some tape in stripes and painted over them with matte topcoat, pulled off the tape and voila! Two stripy accent nails and shiny dots on matte on the rest and I called it a day before I messed something up!
I love the contrast between the shiny and matte, and I think this would make a great subtle Halloween mani. But who needs subtle at Halloween!
