Oh, C'mon! Really?!

I got talked into creating an online arts and crafts business by all my friends and family who have seen the work I do. So I did. And since I started this a couple months ago, I haven't sold a single thing! Not really that surprising to me when you consider how popular it is to sell your crochet and jewelry online, that I'm just starting out and therefore haven't quite figured out my direction and what I'm doing exactly, and that I haven't had as much promotion going on as I could. I figure I have time to get things figured out and make an impact in the coming year, especially if I can come up with different ideas that make me stand out and I set up shop at my local Farmer's Market in the Spring. At this rate I will have plenty of things to offer! lol But, right now my biggest issue is not so much the lack of selling things as it is a lack of creating them. I haven't had the energy or the desire to really get into any projects lately. Oh, I can come up with a million things to do in the future, but I can't seem to get in the mood to actually sit down and work on them. But, I decided to try making a crochet baby dress. Yes, it pangs me to be making a dress for a baby when I'm trying to work things out so I can maybe have one of my own. Yes, it has been screwing with my mood a bit and making me think about what it would be like to be doing this for my own child... and how with my luck I will have a boy and won't be able to make those pretty dresses for my own child! lol But, I have friends who have baby girls and I figured they might be interested in the dresses I make. My problem now is that the pattern I'm using doesn't give me a gauge, only a finished size! How am I supposed to know if the dress I'm working on is the same size as the one in the pattern, especially if I'm using a different hook and it's SUPPOSED to come out bigger that way? I have no idea how to measure the dress for size, and every forum I post on or email I send is getting me nowhere! I had one reply in a forum and the person basically told me what size I should end up with and that changing hook sizes will change the overall size. Not what I was asking about so definitely not helpful. I'm almost done with the dress and it's turning out very pretty, but I have no idea what size it is and I have no one to test it out on! I have heard that some people use dolls as models, so I was looking at dolls online last night. I can't believe how expensive they are! And then I found some that are so realistic looking you would swear they were actual babies! They even BREATHE!! Of course, those types of dolls are even more expensive with an average price of $140, but they were so cute I kept thinking how much I wanted one and how much my husband would so not want to pay for one... story of my life I guess. I always want what I either can't have or I have to jump through numerous flaming hoops and run the gauntlet for....
