My graphic designer eye is always drawn to beautiful simple shapes and patterns. I stumbled across these gorgeous lacey envelopes on Daydream Lily. In fact you can follow the tutorial and make your own thanks to the designer Design Mein. I'm imagining a whole array of colourful cards that you could put in these envelopes and seal with a wax stamp or customised label.
Another paper-based company that I found on Etsy specialise in name-tags for glasses. At Timeless Paper you’ll find unique paper gifts that will put a smile on your face. The simplest ideas are often the ones that are most memorable and I would love to find my name printed on a paper butterfly or dragonfly!
