Making your own strings is great, as said above you can choose colour, length etc.? However buying strings from a reputable string making company is well worth the costs involved, you do need to know what you want but what you order is exactly what you'll get, also when dealing with most you will find that the strings come pre stretched, meaning that when you fit it there is no shooting in period and with compounds you will have zero peep rotation.</p>
Now as for shop made strings, I don't wish to offend but shops make strings as a side line to help out archers, their quality control leaves a lot to be desired, I've seen strings with loose strands, 2 strings sold as the same length with no twists almost 1/2" different in length, serving diameters different sizes on centre serving and serving which as mentioned loosens in use.? Companies who make customs strings as their sole business have a reputation of making great quality strings and so they are that much better and don't have any of the down sides found in shop ones.</p>
I have made strings for myself, and in fact have many unopened large spools of material in many colours, but I only now use these when I want to test things, once I know what I want I will order them.</p>
