I hadn't heard of World Embroidery Day until this morning, but what more appropriate time to post a relevant link or two.
I picked up my needle recently after discovering Nicki Franklin's The Stitchery and her lovely individual kits and monthly Journal subscription.
Caroline Zoob does beautiful work (see also her book on Virginia Woolf's garden), and occasionally has limited edition kits for sale.
If you're in the market for an embroidered project bag (such as the above), look out for new stock in Sherry's shop. Her Instagram gallery shows her style.
I've linked to Mary's blog before, of course; her level of skill is something to aspire to.
Should you be looking to learn embroidery or discover new techniques, the Royal School of Needlework has recently launched some online courses.
