I want to make Briar rose (http://ysolda.com/shop/index.php?main_page=product_info&products_id=1&zenid=87d4a3c77ec0256afbc5238923866b2a) - in fact I've promised to make it for my sister - but I can't find anything appropriate. It's worked at 16 st / " and I'm hoping to make it in something machine washable (because she's an infant teacher and has to be able to get the snot out), including a reasonable proportion of natural fibres. I thought about Sirdar Click, but I think the bolero needs to be drapey so I'm really looking for heavy worsted rather than chunky. Please help, lovely knitters!
