Hello,
The 1 yard at 30" would be 36" by 30 since 1 yard is 36" :) We just put the 1 yard wording on instead of using the 36". It took me a bit to get used to when we changed it.
And we do have a light oatmeal option available. When you are on the Fabric page, click on the Fiddler's Cloth and it will be the second option listed there: STS 14 Count Fiddler's Oatmeal Lite Cloth, just click on that and you will be taken to it's page where you can select the sizes you need. Hope this helps!
