The first item I made was a necklace--and it literally took months! It's been so long since I've been aware of the tutorial that I can't tell you where I first saw it being reblogged, but Livejouranl user oboe_wan made a post in crafty_tardis of the 9th & 10th Doctor's sonic screwdrivers. I spotted it well before mine and my sister's August birthday but was unable to gather the correct beads. I spent hours searching for the exact beads, in stores and online, to no avail. I ended up making my own version and, being a non-Whovian (thus far), I hope that I did it some credit. I purchased the Police Box charm on Etsy already colored blue and put the two together for the first of two Doctor Who related gifts.
The second was a pair of Tardis earrings I spotted on Etsy by user kobsdesigns. I adjusted the design slightly by using two beads instead of one so the Tardis was elongated and a bit more accurate (police boxes are not, after all, short and fat). They were not as simple as expected--painting the "windows" so tiny took a rather steady hand!--but a splash of Triple Thick (glaze by DecoArt) has hopefully sealed in my handiwork.
