The other girls have already given some really great advice (and I agree with everything posted so far)! I don't have a whole lot to add, but I'll just say that I don't usually do calls because I hate turning people down. So, when I'm ready to add a new member, I tend to browse the gallery here at SSD and look for people who use my products in a really awesome way. The best way to get noticed is to make sure you're loading your layouts with my stuff in my designer gallery here. I also like to add people who have a positive attitude and who are a part of the community. I prefer to have a variety of styles on my team (I have everything from "paper scrapped" style to clustering to very minimalist... I like a variety!). So, while I do want exceptional pages, the style of the page isn't as important to me as the execution of whatever style you do.
Also, this part is a biggie for me... I REALLY need people who can scrap with all of my products. So, if you only like 1/2 of what I put out or think you'd have trouble scrapping (for example) with really themey stuff, I'd rather know that up front because nothing hurts more than having to let a team member go when things don't work out.
I count on my CT to promote my business, so I absolutely need team players who are willing to tackle whatever I throw at them.
Like the other girls have said though, just keep at it! If you're doing pages you love, it'll show to the designers when they're looking for team members!
