Abstract
Abstract A method of forming a substrate for needlecraft comprising the steps of providing a planar sheet of metal of a desired shape and size and chemically etching the sheet of metal from both planar surfaces at predetermined to areas to form a pattern of apertures which are suitable for embroidering with thread. The invention also comprises a substrate formed by the above method. The invention further comprises a craft item which is formed by the application of thread to the apertures of the metallic substrate which is formed by the above method.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
247 words
Method of forming a substrate for needlecraft comprising the steps of: (a) providing a sheet of metal of the desired size and shape, said sheet having a top surface and a bottom surface, (b) coating each of said top and bottom surface with a photosensitive material which hardens when exposed to ultraviolet light, (c) applying a transparent mask to the coating on each to at least one of said top and bottom surfaces, said mask having areas which are opaque to ultraviolet light and which represent a desired pattern, (d) subjecting both of said mask covered coating surface and said non-mask covered coating surface to ultraviolet radiation to harden the portions of each of said coatings which lie outside of the opaque areas of the mask, (e) subjecting said sheet of metal to a solution which dissolves the unhardened portions of each coating, (f) subjecting said sheet of metal to an acid solution which dissolves metal from both surfaces at the areas of the sheet which are not covered by the hardened coating, so that apertures are formed in said sheet at said areas, (g) subjecting said sheet of metal to a solution which dissolves the hardened portions of each coating, wherein the said patterns are adapted so that the said apertures comprise a plurality of closely-spaced, small-diameter, generally circular opening, of the type and arrangement used for needlecraft cross-stitching, and (h) electroplating the substrate after removal of the hardened portions of said coating of photosensitive material.
