The first one came about easily. I had been eyeing the sketch at CAS(E) this Sketch and now with an hour until it closes, I decided to use it.
It also came about easily because I just received an order including a Washi Paper Tape Sheet. First, I haven't generally used washi tape. Second, I had no idea what a tape sheet was. But I knew I liked the patterns and the 6x6 paper pad had been out of stock forever, so I thought I'd try the sheets. They weren't quite what I expected - really short - but look how well they work with this sketch!!
