I know it took me a while before I felt ready to move on to the next stage. All the while collecting.
For me, I made scarves for 1 1/2 years (only knitting in the winter) slippers for about the same. Then I did my first sweater which sat waiting to be sewn up for a long time (I think 1 1/2 years). Then last winter... I decided that was that and its been amazing!
So I'd say its okay to wait if your a patient sort of person. Either way, you've got to gulp and try it!
