Policy On Changing, Modifying or Canceling A Current Order:

If you have an order with us and would like to make a change or cancel, we’d love to accommodate. We highly encourage you to reach out as soon as possible. Your order is custom and we want to make it perfect for you!

With a custom piece, once we start on it, it can only be made in your specific dimensions. To modify or cancel an order already in production creates waste in material and labor. We know talking about fees is no fun, yet it is a reality and changes mid production incur real costs. We have kept these fees low and kept them in line with reflecting the efforts of our team's professional work.

Here are the windows within which we accept changes/modifications and any fees associated.

(Change/modification fees must be paid over the phone at the same time as requested. Fees will be deducted from the subtotal and all shipping costs will be fully refunded if canceled.)
