A structural wall unit system includes a plurality of wall units having at least one face being a rotational tessellation. The face has at least two irregular sides extending therefrom. Each side of the wall units have at least one spacer or connector configured to engage other wall units. The structural wall unit system also includes a plurality of starter course units, where each starter course unit has a portion of a primary rotational tessellation element having at least one irregularly shaped side that is an image of the first side or the third side. Each irregularly shaped side of the starter course units have at least one spacer or connector configured to engage the wall units, and the starter course units have at least one straight side. The starter course units and the wall units are configured for assembly as a structural wall having a natural, random appearance.

The technology described herein relates to a design template overlaid on a surrounding series of grid cut lines on the back side of a roll of wrapping paper. Based on juxtaposition within the grid cut lines, the DIY design template cut lines may correspond directly or indirectly to at least a portion of the front side of the wrapping paper decoration. Accordingly, embodiments of the design template may include cut lines for various bow and/or accessory content that, once extracted from the surrounding wrapping paper, may be assembled into a coordinated bow or accessory featuring intentional placement of design content form the front side of the wrapping paper. Additionally, the design template pattern may be repeated along an axis of orientation of the roll of wrapping paper, such that multiple DIY design templates may be repeated across the entire roll wrap bundle.

A method of continuously drawing a series of alpha-numerical characters, an image, or a design or scene on a surface with a drawing instrument in which no line intersects any other line and no portion of characters is retraced. Images and designs can also be incorporated with continuous alpha-numerical characters. Also disclosed is a method of drawing an image on a surface that simulates a three-dimensional object or scene. Products can be created using any of the above-described techniques. Such products can include, but not be limited to greeting cards, postcards, apparel, coffee mugs, toys, games, puzzles, and the like. The surface on which the image is drawn can be made of material suitable for three-dimensional reliefs, so that visually impaired individuals can appreciate the work.

A tracing board assembly includes a transparent sheet having a first surface and a second surface. The first surface including a plurality of hooks providing hook-and-loop adhesion. A frame may be secured to a perimeter of the transparent sheet. An original image abuts the second surface of the transparent sheet and visible through the transparent sheet. The original image may include alphanumeric characters corresponding to colors of yarn. A pen having a tubular body has yarn extending through the tubular body. The pen can be used to adhere the yarn to selected areas of the transparent sheet using the original image as a guide.
