Tension Square in Fair Isle to small
Tension square over rib pattern OK. Over fair isle to small. Do I go to a larger size needle or smaller please?
I would think larger but pattern says smaller.
If I am understanding you correctly, you have done a tension square using the needles recommended by your pattern and your square is smaller than the recommended tension?
If the answer is yes, then you need to go up a size and try again.
Even if the pattern recommends a smaller size, it is much more important to get the tension right, or your garment will be the wrong size.
