I don't spend much time for making those either (macro crafting is boring :P), normally i spend days make only twinthread hq till i get about 200 of them then the next days i turn them all to silver brocade. You should try to gather the cocoon whenever you have chance too (it spawns only once every hour and doesn't require good gear to gather, you should be able to get 25 cocoon each time). Just gather it whenever you can and you will save load of money in the end :)
If you just want to farm MC for yourself (like me) then I think you're better not rushing, would be pretty frustrated and demotivated after awhile :|
