I really need help. Have just finished a baby blanket and even though my tension square seemed correct the size is out. It should measure 24" x 30" but is 21" x 28" and I seem to have knitted many more rows than I should have.
This is the tension instruction; 22sts and 28 rows to 4in over stocking st on 4mm needles. It is sirdar pattern 1926.
I would like to knit another one so really want to get it right this time.
Any help would be appreciated.
