How do you ship them so they don't break?
This is a little tricky...
So, first I put each cookie in its own cellphane bag tied w/ a ribbon. In a bakery box, I place a layer of wax paper and a layer of bubble wrap. Then a layer of small crumpled up pieces of wax paper. Then a layer of cookies w/ crumpled wax paper placed in between and on sides, so the cookies are not touching each other or the box. Then a layer of crumpled wax paper & bubble wrap. Repeat until box is comfortably full, but not stuffed with cookies. Shake box gently, if there is movement, you need more crumpled wax paper between cookies. Wrap entire box in bubble wrap. Place in shipping box full of shipping material of your choice. Make sure it is in firmly, no wiggle room.
This may seem like an overkill, but my cookies have arrived unbroken everytime. Biggest threat is overstuffing box with cookies.
You can also use some type of tin, I just always use a box.
Hope this helps!
