Get involved Knit for your hospitals We need your help to knit and crochet hearts for our Bristol Heart Institute 'yarn bomb' in February 2018! Every knit will help raise funds for our new Bristol Heart Institute Appeal so if you think you can lend a couple of stitches, download our free crochet and knitting patterns here! The heart can be any colour and if you have your own pattern or want to freestyle it that's fine too - knit until your heart's content. The only thing we ask is that they need to be about 4-5 inches in width. We will be using the hearts to decorate the Bristol Heart Institute's atrium in February and people will be invited to make a donation to hang a heart with a message of love, support, hope, remembrance or thanks.
