Hello! i just finished my 2nd scarf on the Ashford SampleIt Loom using a 7.5 (30/10) dpi heddle. I used a lovely yarn- Malabrigo Rios 210 yards, pure Merino superwash 100 gm skein. My instructor helped me calculate yardage, we started with a 60 " warp by 6 " wide and i was left with 70 yds of yarn leftover. I was making this scarf for a petite person as a special gift. I was not aware to calculate the 10% shrinkage and have just taken it off the loom. Prewashed it measures 5 1/2" wide by 36" long without fringe. I am thinking I should start over but unsure of how to make it longer and not run out of yarn. I don't understand all the information to be filled out on the Yarn Calculator. Can anyone help me?
