Abstract
A craft hoop assembly for securing material on which a craft is to be performed comprises an inner hoop or ring having an outer surface and a split outer hoop or ring having an inner surface which is positionable in circumscribing alignment with the inner ring such that the inner surface of the outer ring generally abuts against the outer surface of the inner ring. A bead is integrally formed on either the inner surface of the outer ring or the outer surface of the inner ring. A corresponding groove is formed in the opposing surface of the inner or outer ring respectively. Projections, ridges or bumps are integrally formed on the inner surface of the outer ring or the outer surface of the inner ring or both to increase the gripping effect of the rings on fabric secured therebetween. The projections are preferably formed on said bead. The projections may be randomly arranged or arranged in specific patterns to enhance the gripping effect.
