Hi, i was also in the same boat as you. I did quite a naff training course about 8 years ago and was struggling big time with getting nails to stay on, so decided to give it all up. Then back in June last year decided to giv it another go, so i rang Anne Swaine at Milton Keynes for advice. I ended going up to her for a conversion course, but she did say if i needed more then i would have to take more trainning. Lucky for me, because the conversion course training was so good, i was only there two and a half hours, all done.
I came away ith so much more knowledge, i was able to do a passable set of nails, but in no means a perfect set. The only reason i now class myself as being able to do quite a good set is with constant practice and the help of the wonderful geeks on this site. I consider this site to be the best tool in my workbox. Anyway i think i am saying, ring for advice and take it from there. Good Luck!
