The present disclosure provides for an alignment device used in sewing projects, such as the construction of an inseam. The alignment device may comprise at least one tip, at least one sleeve, and one or more holes. When the alignment device comprises one or more holes, the one or more holes may allow for storage on a wall or other surface via an external hook or knob. The alignment device may further comprise one or more extensions. When the alignment device comprises one or more extensions, the one or more extensions may be coupled to the alignment device via at least one extension mechanism. One alignment device may interface with other alignment devices in a nesting alignment system. When a nesting alignment system is implemented, one or more of the alignment devices may comprise a recess to house at least one smaller alignment device therein for storage purposes. The alignment device may comprise a plastic, wooden, vinyl, or magnetic material, or any combination thereof.

A pillow template system having at least one pillow template which is preferably made of a transparent or semi-transparent material which can be overlaid onto a piece of fabric and can quickly and easily be aligned on the fabric such that any patterns on the fabric are aligned in a desirable way. The template is a frame having an inner edge and an outer edge, with the width of the frame between the inner and outer edges providing a preferable seam allowance. In a preferred embodiment the frame can be nested into a stack with one or more additional frames. The size and shape of the pillow can vary based upon a selected one of the nested frames.

An inflatable cushion for a side of a vehicle is provided, the inflatable cushion having a first portion of material; a second portion of material, the first portion of material being secured to the second portion of material to define the inflatable cushion; wherein at least a portion of a peripheral edge of the inflatable cushion is defined by a seam wherein an inner surface of the first portion is secured to an inner surface of the second portion only by a plurality of stitches; and wherein a strip of a third portion of material is applied to the seam of an outer surface of either the first portion or the second portion when the plurality of stitches are applied.
