Yes, I have my share of "I'm sure I'll use this one day..." things sat in boxes, but sometimes, your creative gut knows when something is right for you.
Around the same time I impulse bought a set of wing charms from Nicole de Bruin Charms, figuring that they would make great... things... lots of things. Lots of potential! Agh! What to make? Being in pairs, and a range of styles and shapes, they're prefect to experiment with.
Roll on a few weeks, I pick up a new very posh purple frock, then realise that this dress needs a set of matched scarab beetle and silver wing jewellery. How fortunate that I have all the parts already! ;)
A final addition was a winged stick pin- meaning than when not worn with a dress, those earrings and bracelet can have a matching flash of jewellery on my lapel or tie.
So the next time you see something, and think "Oh, I HAVE to make something with THAT!" but aren't exactly sure what you are going to make, use this blog post as an excuse to help you validate buying it.
