Feed loom on the wire bundle rather than wire bundle on to the loom. Start the loom by opening the slit on the end of the loom and feeding it over the wires. Separate the loom with your fingers; continue along the loom feeding the slit over the wire assembly. The loom will automatically close around the wires. For a professional way to finish off the ends of the loom use a short piece of thin shrink tube. Heat only enough to shrink the tubing (caution you can melt even hi-temp loom). This gives a great looking termination to the loom.
