Abstract: A sheet material holder assembly comprising a top body having a top surface, a handle projecting generally upward from the top surface, and a first magnetic piece affixed to the top body opposite the top surface and a base having a second magnetic piece, at least a portion of the first magnetic piece aligned atop at least a portion of the second magnetic piece. The base may also include a cradle for receiving a tab of the top body which may be a straightedge having markings. A sheet material may be placed between the top body and the base for use in cutting or other use.

Abstract: A universal design straightedge comprising a body having a top surface and a perimeter bounded by at least one edge, the top surface comprising evenly spaced apart linear rulings perpendicularly disposed to and extending from the edge, some of the linear rulings corresponding to a unit of measure, and some of said linear rulings corresponding to a fraction of the unit of measure, and numerical indicia associated with substantially all of the rulings, substantially all of the numerical indicia substantially centered about a centerline of respective linear rulings, the numerical indicia oriented in standard upright reading position with respect to the edge where the straightedge is arranged with the edge in an underlying relation with respect to the numerical indicia. The numerical indicia associated with the linear rulings corresponding to a fraction of the unit of measure may include a composite of full and fractional numerical indicia.

Abstract: An adaptive easel accommodating multiple orientations, the easel comprising a plurality of legs, at least two of the legs connected to define a first side upon which the easel sits, and at least two of the legs connected to define a second side upon which the easel alternatively sits, at least one of the legs capable of receiving a work surface whereby the easel may sit in a variety of orientations to present a variety of work surface orientations for holding an artistic medium.

Abstract: A self-standing mobile device for cutting sheet material including a body member connected to at least one wheeled axle to translationally move the body member about a surface on which the device self-stands. The body member includes a cutting notch with open and closed ends, the cutting notch positioned with the open end above the at least one wheeled axle. The body member including a contained cutting blade member with cutting edge exposed within the cutting notch closed end, the cutting blade member oriented substantially perpendicularly to the surface on which the device self-stands. A user may engage the device to move the device about the surface on the at least one wheeled axle to cut a sheet of material passing into the cutting notch. Handle and shoulder features, and related methods of cutting sheet material are also disclosed.

Abstract: The present invention is a rolling device for cutting sheet material including a planar body member supported vertically on wheeled axles oriented perpendicularly to the vertical planar body member. The planar body member includes a cutting notch and a contained cutting blade member with a cutting edge exposed within the cutting notch. A handle member is secured to the planar body member and extends upwardly opposite the wheeled axles. A crossbar can be attached to the handle member. A user grasps the handle member, or crossbar, and rolls the planar body member forward on the wheeled axles to cut a sheet of material passing into the cutting notch.
