spoon/spinner questions

[fish4fish]

OK first off how is it best done? i found a site that gave detailed instructions, but to buy the kits you had to buy 10 of the same blade style and color. do any of you know where i could get an assortment of blades and colors. also do you think that it is best that i buy kits of could the spoons or spinners be hand made with supplys from the local ace hardware. also is there a trick to the metal o-rings, i have the damndest time getting them on my lures.
Thanks for any info or ideas you can share.
