I would argue that this is not the case - the sewing process, so far, was mostly the final part of most tasks - usually rushed, because the adaption of the patterns took up most of the time.
And these adaptions are not easy. There was the example of the blouse (episode 2), which was overall too wide on the model - but how could it be altered in a way that it would hang correctly? Or even better - how could this problem have been avoided in the first place?
For a "Sewing Bee"- even one who has done it for many years, some knowledge in the pattern cutting area would not go a miss. It simply widens the scope as to what a "sewing addict" can achieve - the creation of your own, very individual outfits.
Is pattern cutting difficult to learn? I would say that it is not a major stumbling-block - what is, is the perception about it!
Try for yourself!
Happy Pattern Cutting!
