Bolton resident Lyn Slade had never even heard of felting until about six years ago when she was working at a quilt shop and the owner asked her to try it.
Unlike other textile arts, felting is pretty forgiving.
Felting offers nearly instant gratification as the work takes shape fairly quickly.
Yet another method that is often called felting involves agitating a knitted wool item, such as a bag or scarf, in soapy, warm water to compact its fibers, shrinking it.
Leah Adams combines needle and wet felting in colorful geodes, and sells kits for them at her Etsy shop, kneek (short for "knitting geek"), or SpiderFelt.
Adams moved her art studio out of her Seattle home nine months ago, and just moved it again - to gain more felting space.
It comes out as a nice round ball and the smaller the ball, the greater the felting.
Preliminary processing studies carried out in collaboration with CSIRO Textile and Fibre Technology have also shown that knitted fabric made from low felting wool has reduced pilling and shrinkage.
It was the second year that organisers had held a two-day felting course immediately after the show and both times the courses have been so successful that this year organisers are running two.
A two-day felting course making hats with designer and textile artist Lizzie Houghton will run straight after the show on April 29 and 30 and alongside this there will be another two-day course on 3D felting, led by feltmaker Jenny Pepper, a member of the International Feltmakers Association.
