Aspects of the present invention provide devices that receive an item for purchase and an itinerary of a user that includes multiple destinations, each destination defined by a geographic identifier and a corresponding time. Embodiments identify multiple vendor purchase and delivery options for the item, each of the delivery options including at least one of the destinations, wherein the vendor purchase and delivery options have attributes that include a vendor identifier, an item price, a shipping price for the item to one of the plurality of destinations at the corresponding time, and an identifier of a destination at a corresponding time, and wherein the embodiments select one of the vendor purchase and delivery options for the item as a function of determining that the attributes of the selected one meet user preferences.

Embodiments herein are directed to a spatially efficient, multipurpose drawing tool adapted for creating architectural design drawings and capable of drawing lines at regular 15 degree intervals without requiring mechanical reconfiguration. The multipurpose drawing tool is arranged, dimensioned and organized as four sides with a concave vertex opposite three convex vertices, one of which has an angle of 90 degrees and may be quickly manipulated to draw a line at any 15 degree interval, e.g., 15, 30, 45, 60, 75, and 90. The multipurpose drawing tool may also include an aperture having a diameter sized according to a scale for drawing arcs, such as a semi-circular arc depicting a door swing in scaled architectural drawings. The multipurpose drawing tool also addresses a problem of chipped or bent tips for drawing tool vertices (e.g., traditional 30-60-90 triangles and 45-45-90 triangles) by cleaving a portion of each tip.

The present invention is directed to a device, a system and a kit for creating pixel artwork. A device may include a stencil for sidewalk chalk that has a planar body and a plurality of apertures. The stencil may be repositionable on a surface of a substrate and may guide application of a marking device to generate a pixelated grid on the surface of the substrate positioned below the stencil. The pixelated grid may be formed by multiple pixel components that correspond to the stencil. Both a system for creating pixel art and a pixel art kit may include a sidewalk chalk stencil, a plurality of marking devices, and either a pixel assignment or a first instruction. The pixel assignment and the instruction may direct application of the plurality of marking devices to create a pixel artwork of substrate.

A quilt stamps and quilt stamp sets can be used to simplify and expedite the process of cutting and sewing fabric pieces for a patchwork quilt. A quilt stamp can be formed of a transparent material in a desired shape. A stamping side of the quilt stamp includes parallel ridges that are offset from and extend along the outer edges of the shape. The outer ridge can be formed as a continuous ridge while the inner ridge can include repeating gaps thereby forming a dashed pattern. Both the outer and inner ridges can function to stamp lines onto fabric which define where to cut as well as where to sew the fabric.

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.

A geometric divider divides a dimension into equal portions. The geometric divider comprises multiple brachiums, a set of grooves on a first brachium and a second brachium, and multiple slots on at least two brachiums. A base brachium is pivotally connected to a first brachium and a second brachium. A third brachium is configured to slide across the grooves, and corresponding ends of each brachium define multiple mouthpieces to measure the dimension. Each slot is numbered, and a first mouthpiece defined by the base brachium and the first brachium is configured to enclose on the dimension. The third brachium is configured to be selectively pinned in a predetermined numbered slot to determine the number of equal portions to which the dimension is to be divided. An intersection of the third brachium on the dimension divides the dimension to generate a first portion of the equal portions of the dimension.

The technology described herein relates to a spiral art device that allows a user to create and recreate spiral art designs with chalk, and in particular with sidewalk chalk. The spiral art device in accordance with aspects herein comprises one or more stencil pieces and a motor piece. The motor piece is configured to move the stencil piece a predetermined distance around the motor piece, as many times as desired to form the spiral art design. The stencil piece is configured to have multiple securing points that allow the stencil piece to be secured to the motor piece at different angles, further allowing the user to add additional variations to their spiral art design. Design variations may be exponentially multiplied when multiple stencils having differently shaped traceable margins are provided with the spiral art device in accordance with aspects herein.

An educational ruler is a protractor, where the protractor can draw and measure angles. The educational ruler includes a planar disk having a semicircular circumference and labeled in scales along the semicircular circumference; a straight line edge connecting two edges of the semicircular circumference; a through hole on the planar disk; a first edge and a second edge extending from the through hole to the straight line edge; a third edge and a fourth edge extending from the semicircular circumference to the straight line edge. The first edge of the through hole of the educational ruler and the second edge of the through hole of the educational ruler intersect at 90 degrees scale of the planar disk to form the first right angle, and the included angle of the first edge of the through hole of the educational ruler and the straight line edge of the educational ruler is 45 degrees.
