“You only get better at something by doing it more often.”
This statement is true for just about everything in life- cooking, paying bills on time, writing, golf, stalking your ex-boyfriend, sex (with the same person), and even knitting.
So, if you are just starting out as a knitter and your first attempts look like something the cat hacked up, my advice to you is to keep knitting. Trust me, your knitting will improve.
As for that hair ball you just cast off your needles, save it. (Yes, I’m being serious here.) Put it in a ziploc bag and label it with the project name and date that it was created. Enclose a note to yourself that decribes how you feel about the project and knitting as a whole. Then hide it somewhere. Continue knitting and in a year from now, pull out that bag and have a good laugh at yourself in seeing the mess you were in the beginning compared to the pro you are now.
