Need some feedback....

Okay, guys....we're all friends right? I need a little input from all you knitters and crocheters out there in Blogville. My talented niece is a wonderful crafter who loves to make jewelry. She currently lives and works in Houston TX with her new husband. She's done a few shows at her place of work and is starting a website where she and I can sell our goods. She does an excellent job and I think that her jewelry is very very reasonably priced (and I don't spend alot on things....I'm a Jo Ann coupon person, if you know what I mean).
Well, to get to the point here, I told her about stitch and row markers. I personally love the jeweled kind and told her what they are. She designed a few and came up with these.


I think they are awesome! I love them. I'm using them all the time on my crochet and will be using them when I knit. She wants to sell them on the site once it is up and running in the next couple of weeks (I'll have a link to it) but she asked me to ask you for some feedback. What do you think of these? Do you use them? Would you buy them if you saw them on the internet? Do you have any suggestions on how to improve them? What would you pay for a set of three?
Let me know as any input is good input!
I'm gonna close up for the night, but as a teaser, I'm going to show you how cute these look on your projects while you're working on them. We wear jewelry....why not our crochet and knitting? (hey, don't forget the great gifts they would make for friends, family, and your secret pals!!!!) Also, this pic lets me throw in a little Project Spectrum color (yellow) before the month's out....enjoy!
