First the colours. Then squares three rows round. 8 top to bottom. Fronts looks like 3. Makes back 6. Under arm, maybe.Sleeves,5 round 5 long. My sum is...8x14+10x5=112+50=162. One hundred and sixty two squares, sounds a lot but they are small & if I stop I have a blanket...Looking at at least 600grams of wool in a sorted colours. Looking again looks more like 4 rounds. Variant, would want it slightly longer on the back.Pockets are not impossible. Nice looking jacket if the wool isn't to thick.
