It's not as hard as it seems. Take a handful of patterns you like using and get the materials for them. Learn the basics - dubbing, ribbing, tailing, whip finish etc. Practice, practice and practice some more and it will all come good.
Here's a few I'd recommend to start with:
F-Fly straight or curved, very straight forward to tie and uses only a few materials. It will work all season long and cover a multitude of hatches in different sizes and colours.
Pheasant Tail Nymph, my love for this nymph is apparent if you look back through this thread. Again it's very easy to tie and uses a few materials. Keep it thin and make sure it tapers. Play about with bead colour, thoraxs, hotspots and ribbing colour to give you endless variations. Size 12-16 will see you okay all year.
DHE, same as the other two. The hardest thing about this fly is positioning the wing and getting the proportions right. Save this fly until you are a little more confident.
I have spare materials and hooks, I'm sure others will have spare as well. If you would like a selection to get started let me know!
