This seems very annoying at first, but actually makes great sense in many ways and now I love it. First to compare it to the real world it is a lot harder to spin thread or make cloth then to put the pieces together. Which is admittedly a lame answer but the better thought was this:
When you level up you are forced to skill on the thread > cloth. This gives you the mats to make the finished product (5-10 level's below you) and now your not blowing up robes/gloves/hats etc. But rather thread or cloth. When I dinged lvl 30 yesterday for weaving I was making dye'd canvas all from 28-30. Now I have a good supply of the mats needed to make some gil back and synth up some gear to sell. I don't have to worry about breaking a 250k synth. Not all the pieces are like this but at least the body items are much easier then the parts to make them.
Side note: SE did say they were going to adjust some recipe level synths where appropriate.
Ummm which definition of harder
are you referring to exactly?
If you are referring to PHYSICAL LABOR harder, then yes. It is. If you are referring to the fact it takes more SKILL to make cloth than it does clothes, I would argue with you.
First of all, cloth is bought my most tailors in developed countries simply because it is much more cost effective for them to buy it rather than buy the textiles, hire the people to run the machines to separate, clean and weave the textiles into thread then run them through the loom to make cloth. Most of the hard work these days is done by machine in modern countries. In the old days when there weren't any machines, looms and cloth were spun by women and children.
In India and many other not-so-well-off countries of the world, it still is woven by children.
Now, the sewing aspect of the tailoring process is done mostly by machine these days too, but take into account the entire process of tailoring-- making measurements, adjustments, choosing the fabric to use, the colors to put together, designing the outfit. Those are things a machine can't do and requires creativity and a more deeper knowledge of the trade to produce rather than run the shuttle through, pull the harness down, rinse and repeat.
