I would like someone east k which are of better quality quilts, k and I am outside of mexico and I will send a wedding gift, but logically it online all the photos are beautiful but I can not know the quality of the fabric , k known brand is better? vianney or concord?. I totally recommend Vianney, the great advantage over Concord and others is that the quilts look exactly like the catalog and Internet. They are very punctual and they send you the comforter that promise you everything, pillows, sheets, covers and skirting. The fabric is of good quality in both the comforter and the sheets are excellent for cold weather. Look for those brands I can not tell, these only talking about the fabric covers the quilts and the best comforters are goose down, also the most expensive-and the cover is actually the taste of the people, is a cover that is removed to wash and put back. So it is in Europe. .
