through holes 95 in the side of the craft hoop 20 or base plate 70 or through holes 97 in the top surfaces 62 of the bosses 60 or the bottom surface 72 of the base plate 70 proximate to the second bores 75 see fig6 for example with reference to fig3 and 6 the bosses 60 are provided with leg receiving bores 65 that protrude upward from the lower surface 61 of the boss 60 stopping short of emergence through the top surface 62 of the boss 60 a smaller hole 97 may then be provided through that top surface 62 in axial alignment with the center of the associated bore 65 for receiving screws not shown that may then be threaded through these smaller holes 97 in each boss 60 and into the upper ends 85 of the legs 80 within the bores 65 alternatively a small hole 95 may be provided in the side of the boss 60 for receiving a set screw not shown similarly the base plate 70 may be provided with leg receiving bores 75 that protrude downward from the top surface 74 of the base plate 70 stopping short of emergence through the bottom surface 72 of the base plate 70 a smaller hole not shown may then be provided through that bottom surface 72 typically in axial alignment with the center of the associated bore 75 for receiving screws not shown that are then be threaded through these smaller holes and into the lower ends 90 of the legs 80 within the bores.
