General Knitting
1

Just started doing front like to know what it means:

Dec 1 st. at raglan edge on next and every alternate row but at the same time dec 1st at neck edge on every 4 th row from previous dec. until 4sts remain.

I understand the dec on the raglan side, it is the neck decrease I need help with.

Thank you

These neck decreases occur at the same time as the raglan decreases. There was a dec at the neck edge on an earlier row. Call that decrease row, row 1 and then dec on rows 5,9,13,17,21 and so on until there are 4sts remaining.
What is the name of your pattern and designer?
