The pattern skips 7 inches between the boy and the men sizes. I need a 30 inch bust size and the boys go up to 27 inch and the mens start at 34 inches. Would it be easier to decrease or increase, the pattern has yolks front and back so the change has to be made on the yolk as well as the sleeves, neckline etc. Bought the pattern thinking the graduation of sizes would make it easy but it missing the one I need...lol.

It's much easier to make it smaller and as one answer, it's a good idea to do a practice one and the plastic garbage bag idea is good.
I make all my own patterns (don't like the bought ones). I actually use the plastic bags from the store for my patterns - works great; or tissue paper and use a glue stick to put two pieces together if you need a bigger size.
Good luck.

I would try decreasing from the large size. It seems to be more fitting for adults. A hint: Once you think you have the pattern about right, make a mock-up out of newspaper or other scrap paper or even a plastic garbage bag. Tape the "seams" (remember the seam allowances). Try it on. That way you can make adjustments without wasting valuable fabric. You might find something you like or don't like and can change it before making the final version. Good luck!

I found a lot of tutorials, but lots of them are too complicated. But I found the links below. I hope one helps.

This is a good question. So the chest measurement is 30... I think for me, it might be easier to adjust a large size, and make it smaller, because you can just make a fold all the way from the top to the bottom, taking some of it in. Because his shoulders will also have to be adjusted right? If I find a tutorial on video, or something that can help you, I will post it. OK? But what ever you do to the front, you will also have to do it to the back of the pattern.

I hope this helps a little. Check the length of the shirt and the sleeve. They might also have to be adjusted.

I have actually done this with dress and blouse patterns, but you have to make sure that you measure the shoulders, and the chest. Remember that you can always cut a little off the shoulder once he is trying it on, before adding the sleeves. I am still looking for a tutorial.

I think reducing the size will be easier too. I'll keep in touch to let you know how it turns out. Thanks

Please do. I have done both, but I think that reducing the size is a little easier. But... have him close by if you can, or have a shirt that fits him closest to the size you want, so you can compare the pattern to the already made garnment.

I hope it turns out just right.
