When my friends see yarn, whether it's extreme crochet art or yarnbombing, they let me know immediately. This weekend, one friend told me that he'd seen an astonishing thing in his Facebook feed: In Reykjavík, Iceland, a group yarnstormed an ENTIRE BUS! 

The group who did this, Reykjavík Underground Yarnstormers, were asked to do it by the city. Here's what they said on their blog: 

Today is Culture Night in Reykjavík. The whole city is full of music and arts and fun. About 6 weeks ago, we in Reykjavík Underground Yarnstormers were asked to take part by yarnstorming a bus for this night. All bus rides today are free and many people choose to leave the family car at home and use public transport instead since parking in the city center can be hard on days like this. The schedule for the night ends at 23.00 with a huge firework show by the harbor. It is a great day, so off course we wanted to help out by making one of the buses pretty and full of yarn and colors.

To see more photos (there are lots!) of the bus and the intrepid yarnstormers, check out their blog post about the adventure, at Reykjavík Underground Yarnstormers. 

A group in Finland covered a bus in doilies in 2009 (photo above), but Google Translate was of limited use on their Finnish website. If anyone knows more about their project, please fill us in! In the meantime, their photos are absolutely wonderful! 

What's the most astonishing yarn art you've seen? We love finding out about these projects, so we can help our worldwide readers share in the fun.
