Abstract: A method of manufacturing finished articles of flexible plastic material includes formation of a sheet of plastic material with a first portion having a raised pattern on one surface thereof and at least partially curing the sheet. The first portion having the raised pattern is removed from the sheet and a second portion of plastic material having a raised pattern on one surface and of a color contrasting with that of the first portion is formed in that area of the sheet from which the first portion was removed. A plastic backing layer is formed on the sheet and the article thus formed is cured. The backing layer may be of a color contrasting with that of the second portion of plastic material, or the first portion may be allowed to remain and its back surface may be coated with a layer of plastic of a color contrasting with that of the first portion after which the backing layer is applied.
