I'm currently studying to become a Teaching Assistant and volunteering at the local primary school. I happened to wear the hand-knitted cardigan below (my own design but no pattern written I'm afraid) on a training day there and was asked if I could create some knitted items to make story sacks for the reception class, starting with 5 Currant Buns in a Bakers Shop...
I researched the free patterns available and didn't find quite what I wanted so set out to make my own and this is what we have.
The pattern uses the ever popular Stylecraft Special DK, however you could use what DK weight you have to hand rather than buying new yarn as you'll still have a lot left over from each colour. It will make a 3" diameter bun.
It is available through my Ravelry Store or a direct download of the PDF is here download now. It's also a link from my Free Patterns page via the tab at the top.
I'm looking forward to seeing the reception class using these next time I'm in. Hope you have fun making some too x
