I do both Whimsey and Brit + Co. I hate to say it, but they've both kinda gone downhill and are kinda hit or miss.
Whimsey started off REALLY strong. Their first box (my FAVE) was Spoonflower fabric and screenprinting supplies. From there, it kinda slipped to hardware store jewelry (meaning, you actually got a tiny bit of ball chain, some hex nuts and some floss), weird foam shapes, and the occasional bit of (craft quality, not actual embroidery quality) embroidery floss. Then, they caused a huge stir with boxes shipping so late, you got (for example) Feb's box in March. Then, they said they were increasing the charge from $15 to $25 ~ and then backed down ever-so quickly. It's gotten a bit better, but still doesn't seem to be living quite up to their potential, IMO.
Brit + Co started off kewl, too, with a smartphone/tablet friendly gloves project. The box contained conductive fiber thread and gloves ~ you sewed teeny tiny "dots" on the tips of the glove's fingers. Those little "dots" enable you to swipe (use) your smartphone touch screen without taking off your gloves. Another box was LED lit-up balloons. Most recently, it was just several bags of glitter, a blank mousepad and some blank tags. Last one was cardstock and (cheap) embroidery floss to make V-Day cards with.
My advice? Stalk Pick Your Plum ~ you'll find AMAZING stuff posted there every weekday morning at 7am (Central). Tomorrow (Saturday ~ I'm being modded right now, so I don't know when this will post), they're having a HUGE event ~ tons of cool stuff posted at once ~ usually at 60% off. The BIG event is every once in a while, they have grab boxes for $30. In my last one, I got like 8 cast iron handles, a cast iron doorknocker, some embossed metal, tons of scrapbooking supplies, and so much more! Hubs and I figured out the retail value, and it was about $100, easy.
Can you tell I love PYP?!
Anyway, I've been thinking about cancelling both of them ~ I'm just freakin' lazy and it's a PITA to cancel (from what I've been told and what's been complained about). I keep holding out hope that the next box will be better .... :/
