I went to Harrogate Knitting and Stitching show yesterday with my Grandma, I was on the look out for SHCM's and Grandma told me I could have hers as she never uses it anymore. But I mustn't carry or store it vertically as the oil in it will run. Is she right about the oil? I'm struggling to understand how something solid can have oil in it
she even pointed to a lady carrying one and said 'Mine is just like that, a nice big one!' So it doesn't sound any different to the bog-standard green ones!
