should i worry if i do not mount on acid-free?

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

It depends on your climate.  But why chance it, use acid free and your hard work will be enjoyed for years

I have had things ruined, that I didnt 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 Ive seen I think the discoloration starts happening quite quickly and most likely is encouraged by certain environments. I dont think its worth the risk to use non-acid free materials.
