so Im trying to write a rough draft and ive got no clue..

It is supposed to be a introduction to my hobby channel. I have one line so far.

" Hi everyone welcome to moons precious treasures."

Seriously that is all I have. I want the introduction to tell what the channel is about. Like I know I will have at least 1 collectible doll to start with then later I will get the other one. I also want them to know that this is my 1st time ever collecting these items so they will get to watch me experience things such as cleaning them, etc.. for the 1st time. Im just not sure how to word things.

I know I will need to explain what the doll is the one I already have is a lifelike(she is modeled after a real child) Hispanic toddler doll. (body size is that of a newborn.) she is for ages 14 and up. she has full legs and 3/4 arms. Her hair is a glued on wig. her eyes are acrylic.

any way im just not sure how to put all this into words..

okay, I am having trouble even from your description understanding, but I will try and help.

You are doing some sort of hobby channel somewhere? perhaps youtube or a blog? I don't follow you.

Okay, first say your name and what the channel is about. You are collecting lifelike dolls. Simply say that you want to share collecting these dolls with your audience and that you invite them to watching you collect them. Say a little bit about what you will be showing them. Such as you say you are going to chronicle your search for the dolls, your restoration or cleaning of them, and showing their peculiar and noteworthy aspects to your audience.

An introduction doesn't have to be very much, the details about the dolls themselves should not be in the opening text and introduction to your channel, those should be confined to your posts or videos or whatever you are doing. Introductions should only be a paragraph or two at the most, and not really big paragraphs either. The meat of your channels whould be in the posts or the videos or whatever you are doing. Just tell them what your channel is about, and don't get technical. Such things are boring and people are going to back out rather than take part if you go heavy into the technical stuff like you did above.

If you have any more questions feel free to ask. I'm happy to help where I can.

I'd mention what got you into the hobby and your background. People love to hear a backstory and understand your passion better.
