Shipping Rate for Specific Item

Is there any way to assign a flat shipping price to a certain item? I have wooden boxes and I need to add $11 to the shipping anytime anyone orders one. I was considering building it into the price, however, I thought I might be able to just link a dollar amount for shipping directly to the item.

Would Manage SKUs->Edit->Advanced->Shipping SKU work? You’d have to define the SKU as another product but it gets you there? I’m not sure what the side effects might be, however…
