You can enhance the flavor of cheap chocolate in a variety of ways http://candy.about.com/od/workingwithchocolate/a/chocflavors.htm I find just a DROP of 1-2 oil-based extracts (Michael's probably has some) are more than sufficient to give a little depth I've even made a paste of cocoa powder and coconut oil to get some cheap "candy coating" up to better snuff. Wouldn't do ganache even with good chocolate unless there's liqueur in it, heh-heh. You can get a tiny bottle of it for $2 at the liquor store.
You should be wary of promising folks tons of traffic or anything else unless you've got a proven track record or you could damage what reputation you have. Your two sponsors on your blog, one hasn't posted an entry since March, and the other only 1-2 times per month. Beyond that, you have 100+ members, which isn't indicative of the tons of traffic you're promising. Your blog posts have few comments. Just being realistic here, is all. A big giveaway isn't going to improve your ratings, either. People might sign up to get free stuff, but once it's over, they'll just disappear again. You have to ask yourself what you want your blog to BE, then focus like a laser beam on getting it there in CONTENT, not GIMMICKS.
Getting out the ole thesaurus (that's usually my first recommendation), I think the word "allure" is easy to work with. D'allure, Bellallure (has too many online, but maybe BDAllure), etc. Just don't overthink it and write down as many names as pop out of your brain and work with the finalists until you get the "it" name. The problem with mystical creatures is that seduction usually means imminent death, and also their names are too hard for regular folks to pronounce.
You can go into any craft store and find tons of kits, so it's not a matter of "will these kits sell?", but "how do I grab some of those kit-buying customers?". That's always the challenge whether you're selling a kit or a ready-made product.
$8-10 sounds right. $2 and 15 minutes, you can make a ton of those and make money. Well, somebody has to buy them first, heh. They're certainly cute, but so are a lot of other earrings, so the real challenge is to find customers.
You could actually use it for everything, but it will be slower going. If your fabric is stretchy or slippery, a walking foot is a good choice to keep the top and bottom layers even. I like to use it to sew around the tops of bags because a regular foot will produce a bit of stretch on the top layer and the last inch of it will always have a stupid wrinkle in it.
Not all bed skirt "white material" is created equal, but there's no reason why any fabricy stuff can't be used as interfacing. Folks use lots of different stuff for interfacing. If the thickness and stiffness is up to your standards on a particular project, then go for it.
