Pick Movement

Hi, this is my first post on here, I dont know if its in the right place or if this topic has been covered before. I cant find it if it has !!

I havent been playing long at all so this problem may and probably is entirely down to practice.

When playing the pick moves back inbetween my thumb and index finger. It sounds a simple thing but I'm sure this is holding my playing back considerably. Everything starts fine, hitting the strings fine and then it gets to the point I can no longer compensate. I have considered super glue !!!

I have tried a variety of different picks, many people have said they subconsiously adjust the pick. When I try and adjust mid flow it all goes pear shaped.

If anyone has any suggestions other than super glue they would be greatly appreciated.

Thanks, Sam
