Machine Embroidery Stabilizer Backing Mixed Lot of Remnants?.
PLEASE READ
Okay so I'm selling these items for a friend whose mother passed away and she had several Bernini machines and was very much into Embroidery and quilting. I am not very knowledgeable about such things, so I'm learning as I go.
Any information I post below is information that I found on similar listings and I am presuming that these sellers know about their items but I cannot guarantee it.
I'm going to have lots of accessories and machines for sale within the next few days .
DESCRIPTION
I don't know the exact name or description of this brand but I do know it is the backing for embroidery because I've seen it on the back of embroidery LOL.
This is a very lightweight plastic waffle material that is almost sheer. If anybody could help me out with a better description I would love to know.
Lot includes:-
3 sheets 60" long x 19" wide
1 Sheet 72" long x 19" wide
8 roughly cut 8-10" squares
Please make sure to look at all the pictures before purchasing, this is a small individual business, and my only form of income, sold as is.
I try to take lots of pictures, and try to give accurate descriptions, but I do make mistakes . If you are totally dissatisfied, or I made a mistake in my listing, I will do my best to make you happy, just contact me first. I welcome questions and answer quickly.
All used items are cleaned whenever possible prior to sale.
If you check out my store you'll see I have a high positive rating.
