Very good, consistent quality for a very reasonable price.
One thing I would like to note is that the business is very busy, and can miss deadlines (often by a week or more), though to be fair the upholstery business seems to have very long deadlines (sometimes two months or more).
Also, when doing anything upholstery, it helps to know exactly what you want. If you want lining in your curtains, see how it's done on the examples that are on site. Be thorough. Look at how the lining is sewn on all sides. If you want the lining sewn at the bottom (which H Sewing usually does not do), mention it.
Roman Shades were a little different than I had pictured. Again, I recommend looking at the examples at the store to see if the end product would be to your taste.
