How would I connect multiple RJ45 crossover cables together?
On my home network, I have 2 switches that I want to connect together. I have 3 separate RJ45 cables, and the cables connect together with couplers. Currently, all 3 of the cables are crossovers. The combined length of all of the cables is around 115 feet. One end of each of the cables has a crossover pin configuration, and the other end has a straight-through pin configuration. Would having this setup on my home network cause any problems, like packet loss or slower speeds? The connection appears to be okay, but I am just curious.

Hi!
As you may know, any odd number off crossover cables should work. And any even number of cables should fail. Some switches can use straight cables and if you have 2 of them it would work anyway, as someone pointed at here...
As the combined length is around 115 feets, relatively short, the eventual loss of signal due to the 2 couplers is not that important.
Keep in mind that is important to use pin pairs 1-2 and 3-6 using the SAME twisted pairs to keep you from loss of signal. When using a single cable any pair is ok, but when you have couplers things can get bad ;) since the connection could break. In short: use the standard color assignment...

Actually if you connect two crossovers you have a straight through cable!
They cross twice thus = not crossed.
How you are working is because you must need a crossover to work! Yes you might have issues, however, most network cards today are "auto" sense so they will find and use the signal in spite of the transmit/receive cross connect.
As a general statement using ONE cable is better than using three because each connection point is a point of failure!
