Yarnbombing is a joyful thing: We look out our windows to find that the trees have grown socks and that flowers have bloomed on chain-link fences, and nobody knows exactly how that came to be — or even wants to know. Yarnbombing is done in secret — although around here, you'd rarely be wrong if you guessed that the deed had been done by members of Denver's number-one yarnbombing squad, the Ladies Fancywork Society. So it was almost a slap in the face to their fans — a gentle, funny one — when MCA Denver asked the LFS to come out from undercover to knit a huge temporary curtain to protect the museum's reception desk from piercing winter winds whistling through the building's open entryway. Titled "Fancygasm," it's just that: a knitted patchwork splash of wintry colors that awes and surprises guests before they've even entered the museum proper. Oh, what a web they weave.
