Buying a lot of cable and making your own really comes into its own
when you are cabling either a long distance or large area. The cost
of a reel and the tools to do it is far far less than buying cables.
Look out for cheap prices too as i'm pretty sure when i did buy some
for a client i had the at $1 for a 3m Cat5.
couple other things to add to the excellent recommendations so far..
The most common problems other then the above when
making your own cables are:
1. not getting the cables in the right order. You
can tell this before you crimp if your carefull
2. not pushing the individual wires of cable to the
ends of the connector when crimping.
3. not having the individual wires at equal lengths
or close to it.
recommended when the main cable is stripped to fan out the inner
wires, put them in the correct order and then trim the lot with
scissors. That if lucky can be slid into the connector.
4. cutting any of the individual wires.
make sure you are running of a correct diagram (check a few websites
and make sure they all say the same thing - i don't have a diagram
here or i would write it here). Actually just grab a working cable
and work off that.
make sure you aren't running off a crossover diagram (used to create
cables to connect computers directly without a hub/switch)
it may have been possible you got dud cables and never had a chance
to create working ones.

as far as i know a t100 connection only uses 4 of the wires on the
RG45 connection and the individual wires should be able to be put in
any order as long as it corresponds at the other end. I've seen a
couple made up cables that are done like this but it never looks very
good.
