The store mainly offers inexpensive fabrics. The sellers are polite.
A serious disadvantage is that no one knows the real composition of the fabric. "This is a fabric with wool," and no one knows 10% of wool or 80%, and no one knows what is in the composition except wool...and so it is with all fabrics...
I sewed the dress, they did it carefully, but they did not have time to do it at the appointed time, they forgot to do the overlock, they fixed it after a reminder.
