Abstract: Three-dimensional decorative articles are produced from blanks of heat-shrinkable plastic sheet material, using a mold base having an outer surface with a recess over which a blank is placed, and a convex mold insert that moves into the recess by gravity as the blank softens and cooperates with the interior wall of the recess to shape the sheet material into a three-dimensional decorative article. A guide peg extends outward from the bottom of the recess past the outer surface of the mold base and extends through a hole formed in the blank, and through a guide hole in the mold insert to support the mold insert before heating and to guide the mold insert as it moves into the recess of the mold base.

Abstract: A decorated strip of coated, heat-shrinkable, plastic sheet material is placed on a mold comprising a cylindrical mold body, and attachment means, preferably in the form of two parallel pins extending toward the cylindrical mold body from a pin-supporting wall, and with their ends remote from the wall spaced a short distance from the cylindrical mold body. Holes adjacent the ends of the strip are engaged with the pins. Upon heating in an oven, the strip shrinks, forming a resiliently expansible finger ring, which can be removed from the mold by disengagement from the pins.

Abstract: A decorated strip of coated, heat-shrinkable, plastic sheet material is placed in a spiral slot formed in a silicone rubber mold. The spiral slot is defined by a spiral wall having a uniform wall thickness. Upon heating in an oven, the material shrinks, forming a resiliently expansible arc-shaped band that can be worn as a bracelet or wristband.

Abstract: A peg loom is composed of a frame having a series of detents for receiving end portions of elongated pegs, and a notched cross member spaced form the series of detents to maintain the pegs in parallel relationship to one another during the weaving process. The cross member can be used as a comb to move a weft structure along the pegs periodically as weaving progresses and the notches in the cross member have resilient protrusions that maintain the cross member in engagement with the notches during the movement of the weft structure. A threading tool is provided for threading warp yarns to eyes at the ends of the elongated pegs and also for threading a weft yarn onto a tubular weaving guide. The threading tool includes a loop which is retracted for storage by a movable bead.

Abstract: A clasp for use in making jewelry comprises an elongated hollow tube having an opening at least at one of its ends and an elongated, Z-shaped slot having a first section extending from the open end of the tube to a first intermediate location, a second section extending approximately circumferentially from the first intermediate location to a second intermediate location, and a third section extending from the second intermediate location to a third intermediate location. Flexible decorative strands of material, having enlarged ends larger than the slot, can be slid into the opening of the slot and into the third section, where they remain unless deliberate manipulations are undertaken to remove the strands.
