Unless you are very famous, 'in the public eye', or have some other special claim to fame, then I don't know if Twitter has much to offer you.
I have been on for several years, and joined originally when Lily Allen was bringing out her first CDs as I had hoped to make personal contact with her. I follow her Tweets (most of which I don't really understand) but have only had ONE reply from her, which was when I informed her about bad info being circulated, but she said she already knew about it. When she had her daughters I had hoped she might tell her 4 million fans about them, but she seems overprotective of them. We get to see pictures of Prince George, but the only shots I've seen of Lily's girls, features have been pixilated out!
Your best bet might be to 'follow' others in a similar line (if they are on Twitter; I know they have websites) such as Kaffe Fassett or Jean Greenhowe; I assume you know their work. You might be able to make contact, or gain access to their 'followers'.
A few singers who are successful professionals, but less well known than Lily Allen, I have made some contact with, but nothing to get excited about.
As far as I know, Tweets are only seen by people who are 'following' you, and unlike MN, you can't 'Message' people unless they are following you. (That is as I understand it, but I am prepared to be corrected by someone more expert than me). This is why I much prefer MN, as you can actually make contact with people. I only posted replies to queries on Primary Ed for years (I'm a retired TA, having worked in schools for 25 years) but now I reply on all sorts of things.
My wife is a keen knitter, and has done many Jean Greenhowe dolls, to a high standard, over the past 25 years, a stand-out one being Great Uncle Angus, with his bagpipes!
I don't know who does them, but there are patterns for Eddie Stobart trucks I believe, though the pictures I saw weren't that impressive.
Good luck, and I'll have a look at your Tweet sometime.
