También es importante lavarlo para limpiar el apresto o almidón que les ponen a las telas, y luego plancharlo sin añadir ningun producto al planchado. El almidón o apresto hace que el bordado se vuelva amarillo
I have had things ruined, that I didn't frame but purchased at auctions or estate sales that were framed with non-acid free mats and they are significantly discolored. I will estimate the pieces were framed probably 10 to 20 years ago. Based on what I've seen I think the discoloration starts happening quite quickly and most likely is encouraged by certain environments. I don't think it's worth the risk to use non-acid free materials.
