When I first learned to knit one of my early projects was a Fair-isle vest with short rowed vest points. No one told me it was too hard for me, so I knit it. It turned out to be a beautiful garment and I wore that vest for many years. It wasn't until I began to socialize with other knitters that I found out the vest I had made was considered to be an advanced project by most.
Have you ever wondered how much your knitting would improve if you stopped worrying about taking on projects that are too hard? In my case I was too inexperienced to know that, so I just did what the pattern told me to and I was successful. Now we have so many more resources to teach us techniques even if we don't have an advanced knitter immediately available to answer our questions. Help is just a few keystrokes away.
