A mess-free coloring system comprising a coloring medium and optionally one or more coloring utensils is disclosed. The coloring medium can include a substrate with or without decorative effects and one or more coating layers on a surface of the substrate. In various examples, the one or more coating layers include a color-triggering developer, e.g., in the form of a substantially clear resin, and an opaque pigment. Decorative effects integrated with or disposed on the substrate, while initially obscured by the one or more coating layers, can be revealed when the coating layers are mixed with at least one color precursor stored and dispensed from a coloring utensil. The opaque pigment is selected and configured such that, upon receipt of at least one color precursor by the one or more coating layers, a change in the pigment's reflective index occurs as the pigment dissolves into the clear resin developer.

An embroidery decoration has an outer frame and a stitching plate. The stitching plate is detachably mounted in the outer frame. An outer periphery of the stitching plate abuts an inner periphery of the outer frame. The stitching plate has multiple through holes formed through the plate surfaces for needles and threads to directly pass through for stitching on the stitching plate. After stitching, the outer frame, the stitching plate and the thread on the stitching plate form the end product. The stitching plate is solid in a fixed shape, thereby eliminating the problem of loosening and facilitating convenience in stitching. The embroidery decoration is mainly composed of two components made by plastic injection molding, such that the manufacturing cost is reduced.

An image display including an image substrate and a support structure. The image substrate has an image printed on a first surface. The support structure can include a front sheet and a plurality of side strips extending from the front sheet. The image substrate can be adhered to an external surface of the front sheet so that the front sheet forms a rigid backing for the image substrate. A variety of image substrates are provided.

A kit and method for assembling a frame supporting a stretched sheet includes a set of four stretcher bars, a set of braces, a stretching lever, and a sheet of material. A first stretcher bar can be initially attached to a first edge of the sheet. Remaining second, third, and fourth stretcher bars can be assembled with the first stretcher bar and corner braces to form a frame that rests upon the sheet. The stretching lever can be used to stretch the sheet between opposing stretcher bars just before the sheet is attached to a stretcher bar. The method of using a stretching lever as opposed to stretching pliers greatly reduces the time and difficulty of uniformly stretching the sheet.

A detachable board includes a body, a filling foam, and mounting patches. The body includes a recessed area on the back of the body made by stamping process. The filling foam forms mounting slots with an inner wall and corners of the recessed area rim. During installation, the filling foam and the mounting patches are snuggly fitted in the recessed area. The mounting patch comprises a release film layer, an adhesive layer, and a substrate layer. The substrate layer is in contact with the body of the detachable board, and the adhesive layer is pasted onto a fixed surface for mounting the detachable board onto the fixed surface.

A frame assembly includes a frame base and a rear panel including a plurality of side walls that are configured to be received within a plurality of side walls of the frame base. Along an external surface of each side wall of the rear panel there is at least one locking tab that is configured for reception within one corresponding locking opening of the frame base when the rear panel is inserted into the frame base so as couple the rear panel to the frame base in a snap-fitting manner and permit a canvas substrate to be captured therebetween for holding the canvas substrate across a front face of the frame base.

A canvas fixing device for an aluminum canvas frame includes: canvas frame bodies each made of a lightweight metal, a fixing groove formed on the rear surface thereof and having a support protrusion, a coupling groove formed on the rear surface thereof, and a support wall formed between the fixing groove and the coupling groove and having a lower height than the rear wall thereof; and fixing pins molded with a thin plate and having a fixing protruding portion and wedge-shaped protrusions formed on top side thereof and an elastic portion bentedly formed on bottom side thereof, the elastic portion having a support piece formed by bending the bottom of the fixing pin, an elastic piece formed by bending the end of the support piece, and an extension protrusion extending from the elastic piece and having a locking projection protruding therefrom.
