try you tube there are tons of free tutorials on there, but also find fellow tiers check with your local fly shop sometimes there are tie ins and such. I worked in a fly shop that had been open for almost 30 years and once a month the guys who originally tied for the shop would come in and do a tie in. I did not tie when I first started working there but after a while it becomes contagious videos are helpfull as are books but nothing is as helpfull as in person expertise.
