Yarnbombing is usually used as a form of decoration, brightening up public spaces and injecting a little creativity into the local community.
More fun than functional, its main purpose is usually to make areas look more appealing or amusing.
However, there are ways in which you can use knitting and crocheting skills outdoors in a more practical way.
Professional crochet pattern designer Janet Taylor revealed this week that she used her crochet talents to help a group of stricken chicks she found lying on the road after their nest fell from a tree.
Hull Daily Mail reports that she then decided to make a replacement by turning a hat she had been crocheting into a nest.
Mrs Taylor then sewed it into the tree and stuffed it with feathers from the old nest to ensure the goldcrest chicks and parent birds would embrace their new home.
The Driffield-based designer told the publication: “I just wondered what I could do as I couldn’t just leave them. I didn’t think it would work at all.”
However, she said that the next morning she saw the parents flying to and from the nest feeding their young.
After a few days of keeping watch on the nest Mrs Taylor saw all three birds looking healthy and well fed and added “I was delighted as, when I first found them, I didn’t think they had much of a chance… I’m just pleased I managed to save them”.
The goldcrest is the smallest bird in the UK and can be fairly rare to spot. Bird-watchers can look out for a black and yellow stripe on their heads with an orange centre in males. The rest of the feathers appear greyish-green, with a slightly paler belly.
They survive on small insects largely, using their long narrow beaks to help them delve into tree bark and inside plants to hunt their tiny prey.
