Straw is an agricultural byproduct consisting of the dry stalks of cereal plants after the grain and chaff have been removed. It makes up about half of the yield of cereal crops such as barley, oats, rice, rye and wheat. There are several styles of straw hats, but all of them are woven using some form of plant fibre. Many of these hats are formed in a similar way to felt hats; they are softened by steam or by submersion in hot water, and then formed by hand or over a hat block.
This is not your hat, as Magritte would say.
It's similar, sure, but it's not the same. Because your hat, the one you're buying, will be made expressly for you immediately after your purchase. It will be a unique artwork.
Delivery will take more or less time depending on the creative and development process.
