Oh no! Thanks to Jessica, who left a comment about a very co-incidental word (dressmakers, if you're interested!) she'd been asked to verify through Captcha, I discovered it was in operation on my blog! I honestly thought I'd removed it.
Big apologies - I've removed it now, and I owe everyone that's commented extra thanks. I know how irritating Captcha is and how hard some of the words are. Occasionally, I've even given up on leaving a comment on other people's blogs after the third attempt to guess an especially blurry word.
I'm now relying on Blogger's own spam filter and as a precaution have switched off anonymous comments. I'm sure this won't be a problem with any of you :). If I get a lot of spam I'll consider moving - maybe to Wordpress? We'll see what happens.
In the meantime THANK YOU so much for your patience and leaving comments despite having to jump this hideous hurdle. You're the best!
Happy sewing, 'till next time!
