A ground penetrating radar stencil and system for using the same is provided. The stencils are reusable. The stencils are foldable, allowing for storing and transportation. A first data collection grid stencil is used to mark a grid followed by alternative target marking stencils used to mark utility line and structural support lines. Indelible stencil paint/ink is applied on and through the stencils onto the concrete surfaces to provide for a permanent, standardized and consistent marking of critical embedded infrastructure. The system allows for a uniform collecting and recording of the scanning data results for future reference and work in the same area.

An invisible tracing or drawing activity utilizes a universal self-adjusting UV lamp which forms part of or can attach to a grip which slides onto most writing instruments. The grip is flexible and can stretch to adjust so as to accommodate various sizes of drawing utensils. Blueish (UV) light will reveal hidden artwork that can be traced, drawn, or colored within. Coloring books act as collections of different and unique hidden artwork that can occupy a child's attention for hours, days, or in some circumstances, even weeks.

A kit for making a sign utilizing a router includes a plurality of interlocking templates that can be utilized to form the letters for a sign. The kit includes two or more templates that are positioned in the same location on a board in a sequence to form a single letter, number or symbol with an island with an uninterrupted perimeter. The kit also includes a guide bushing that is secured to the router bit to prevent the router bit from gouging into the templates.

The present invention relates to a drawing assisting tool, comprising at least one thin template with a set of solid and dashed grooved lines, in which said grooved lines are adapted to guide the drawing of at least one complete spatial body on a flat surface.

A combinational template and scale ruler to accurately draw three-dimensional (3D) drawing is disclosed. The scale ruler is a transparent plate, which includes a plurality of apertures disposed at a middle portion. Each aperture defines a substantially continuous linear aperture corresponding to a visible edge of 3D shape. A plurality of indicium is juxtaposed around each aperture to facilitate drawing of the 3D shape. The plurality of indicium is inscribed in surface of the scale ruler. The plurality of indicium is graduated to define angle and size factor of the aperture to facilitate drawing of the 3D shape. The plurality of indicium further includes 3D shape of a cube of the aperture. The plurality of indicium includes information regarding the classification of the 3D shape. The plurality of apertures is arranged in groups and subgroups of the groups based on a type of projection of the 3D shape.

A stencil for use in stenciling complex symbols incorporates a stencil substrate employing a flexible material, having a plurality of symbols arranged thereon. A plurality of folding stiffeners are incorporated in the substrate, each stiffener being positioned to split symbols having stencil cutouts forming isolated elements within an interior of the symbol. The stiffeners are foldable about a vertex, to collapse into a raised position and bring together the split symbol, with the stiffeners supporting the isolated elements created by the cutouts and portions of the stencil cutouts forming the symbols that extend into coincident channels in the folding stiffeners, to bridge adjoining portions of said split characters.

The present invention teaches a tear away quilting template system comprising a row template and at least one corner template. The row template and at least one corner template each feature a solid line pattern and a dashed line pattern. The dashed line pattern is designed to match and correspond with portions of the solid line pattern.
