I got these pretty charms and the bracelet to hang them on from Primark (I don’t think they exist in the US, but I bet Forever21 has something close) with the intention of using them as stitch markers. They work like a charm (ho ho) and would make great (inexpensive) gifts for knitting friends. You can then purchase them charms on other special occasions to add to their collection. Stitch markers with clips would also work; I know Atomic Knitting makes beautiful ones.
The regular charms from Primark fit needles up to 3.5mm.
This is a colourwork hat I’m working on with designs from the Perpetual Colourwork Calendar (October). I’ve already attempted filming one tutorial about creating your own colourwork charts, but the lighting was so poor that I think I will try again. Sorry for the delay!
The needles are KnitPro Symfonie (short 3mms with 60cm cable) and the yarn is Pure Wool Superwash from Nako.
If you go to the Primark in Birmingham, say hello to the Bullring Bull in his woolly jumper. :)
