Hi,
Writing is really tricky and just takes lots and lots of practice. When not doing cakes I practice different writing and printing techniques. The other trick (which I'm not very good at) is using piping gel transfers. Use piping gel on parchment and write the message then transfer it on to the cake. I just avoid writing on the cakes as much as possible since it's tricky. It's just an art in itself and takes time to master. Good luck
I have always had a problem writing on cakes. I found an article on this
in an American Cake Decorating Magazine. I made a copy of it using the practice board, put it under the clear sheet and practice, practice, practice
If you would like a copy send your email address in PM

I have shaky hands too! The best thing I've found is to make sure your icing is the perfect flowing consistency (I really like using piping gel to thin buttercream) and then it's almost like writing with a pen.
And, of course, practice, practice, practice makes perfect!
OK Ladies some of you sent a PM asking for a copy of a templete
I copied out of an ACD magazine. I thought " no problem."
Welllllllllllllll big problem our scaner is on my husband's computer.
So thought .... scan it send it to my computer send an attachment to
ladies using my email WA LA!!!!!!!! well there is a problem it won't add attachment to email.
I found the templete in a sept/oct 1996. Can anyone help me out after promising the ladies I would send it to them. 
I am sooooooo frustrated right now I'm going to go bake a cake
I am in wilton class one and I have a heck of a time with writing. I have practiced and used the piping gel and still no luck. I dont know if it is because I am trying to concentrate to hard or what.
If anything requires me to write I will avoid it, I really hope this skill comes to me and soon.

i feel the key is to let it flow, make sure your icing is soft enough and hold your hand with the other hand, squeeze the bag and then move, move swiftly but not too fast otherwise you will break the icing. practise on the back of the cake pan so you can practise sizing your letters.
aww love your care bear icon
just keep practicing...last year i hated my writing...but this year its really gotten lots better...i used to get my mom to come do the birthday message for me lol...but now she says im better than her
anyway, i found that after i would print the message in a font that i liked on my computer and then print it out on paper and lay it on my decorating counter to look at as i wrote, it really helped me with placement and everything....maybe im kooky...but it helped 
also doing a practice run before you do the actual message on the cake can help loosen up and relax your hands, just do a quickie on a paper plate then the cake doesnt seem so scary...hope this helps
i go to my computer, type out my words, find a font, then size it to fit and print. Then I lay out wax paer over what I have printed and pipe melted white or regular chocolate on the wax paper over the words. If it's going on a flat spot I let it lay flat. If it's going on the curved side of a cake i lay the wax paper with the chocolate already on it on the curve of the size pan I baked the cake in. When it sets up you just carefully peel away the paper and place it on sticky icing on the cake or pipe a little icing on the back. It's a lot easier and less stressful than piping directly on a cake. If you use a cursive font you'll have a whole word in one piece to place on the cake...
I wish I had some magical tips to share, but I don't. 
As others have said, you just have to practice, practice, and practice some more. It took me several years before I was happy with my writing, and even now, I still have "off days". It's just one of those skills that you have to keep working at. Don't get discouraged ... it will come!
I have had problems with writing as well. I use my computer to type out the message in a graphics program, find the font I want, mirror the image and then print it out. Then I put a piece of wax paper over that and trace it with royal icing. After it dries I use it to press into the slightly crusted bc or rbc. It leaves a nice imprint that I can then follow with my piping bag & tip.
