RE: Filters for masks
3M 2200 best for virus protection
I’d been wondering about the so-called filters that were to go into the masks and finally Bob, my tech guy, did some research and found out that furnace and air conditioner filters could be cut up for inserting in the masks. I couldn’t imagine how that would be, especially when he bought one at the hardware store and brought it to me. So, I checked the web and found just what I needed: the package, how to open it, what to use and what to throw away. Then it showed how to cut out the pieces for the filters to insert. Here is the LINK to that YouTube video.
In preparation for making the hem, I protected the last weft by pulling warps periodically back into the cloth just like in a previous post. (This prevents the raw edge from unravelling.)
I turned the hem to the wrong side and ironed only on the fold to make a crease there. Note that I didn’t iron the cut edge so as not to make an impression on the right side.
I used this iron-on adhesive rather than sewing the hem down. This type in the red package is meant to iron in place and make a permanent bond. It used to come by the yard but I’ve only seen it in these smaller packages lately. It is available from fabric stores and Amazon. Be sure the package says Ultrahold” and not “Lite”. It was not in the interfacing area of the fabric store, but in an aisle where applique supplies were located.
This shows the adhesive ironed paper-side up in place inside where the hem is to be. Since you won’t be ironing on the raw edge, place the adhesive near the crease where the hem will be turned to the wrong side.
Peel off the paper in preparation for the final ironing.
Turn the hem under, enclosing the adhesive and iron. Remember to only iron on the fold –not on the edge of the hem to prevent an impression that would show on the right side.
Note that there is a purple package (Lite) that isn’t meant for ironing permanently but requires stitching down. The adhesive just holds a piece in place in preparation for stitching to hold it permanently in place. It comes by the yard or in packages with larger amount than the Ultrahold in the red package.
