sunnyhope- I added you to the blogs I follow. Cute blog! I wish I had started one when I first started quilting so I had a complete record of everything I have made.
littlehud- A blog is sort of an online diary like liwilliams said. That is how I use mine. It is a public "page" of your own that you can use however you like to post pictures and/or essay-like or note-like posts. Some people use it to get their name out there for their business, some use it to update their families, some use it to connect with other people.
I use mine almost solely for quilting, but some pics of my cats and kids work their way in. I started one to join a challenge and then liked it so I kept it up. I have connected a lot of awesome quilters with my blog. Some people like a lot of traffic through their blog. I don't really care how many people SEE my blog, but I like when the ones who stop there leave a comment. I try to always respond to comments with an email. This is a great way to make friends.
Lacelady- I do my blog through blogger. I find it fairly user-friendly. Here and there you will have a day when you can't rearrange pictures, but I haven't had that problem in a while. If you just want to put pics online, you can put them on Flickr. I have a Flickr account and you can join quilt groups on there.
(This is my page, but you should be able to find a button on there to start your own.)
Here is my blog and a couple of my favorites:
I have 66 that I follow so I don't have room to list all of them- LOL!
I have lots of others that I like, just tried to pick the ones who mostly have lots of quilt pictures.
