All panels are 36" wide before trimming by installer (about 1/4 to 1/2 inch is trimmed off). Sizes vary from 4'/6' to 10'/12' (4'/6' means 4 feet of design on a 6 foot panel). Delivery for orders of approximately 10 panels is about 8 - 10 weeks after approval of samples and any diagrams. A 50% deposit is required prior to ordering, with the balance due prior to shipping of the product. We recommend installation be completed by a certified paper hanger. Hand painting creates inherently unique nuances between panels and this is not a defect. It is the responsibility of the customer to approve the order prior to installation.
