Need help. This is my second attempt at blanket weaving using wool yarn. I was trying a project from a Handwoven e book called Warm and Cozy plaid blanket using Nature Spun Sport 3ply. I sett at 12epi as that was suppose to help achieve an even beat. Ppi were to be 12. I found this very hard to achieve an even beat with. I was using a temple. What am I doing wrong. I tried being very consistent but I just could not keep a nice straight twill line and achieve the correct ppi. Any suggestions would be very helpful. Thanks in advance.
