Welcome but please don't be discouraged. Check out some quilting books from the library that will help. There's also tons of information on quilting on the 'net. There's a lot of us that have never had any kind of "classes", we just taught ourselves. As beginners, they may not be "perfect" but as we continue we improve.
You don't want to "iron" your seams though, you want to "press" them. Big difference!
