I always use 2 layers of wss when making fsl. I can't respond to your question as I have never used badgemaster. I'm sure others here have so you should get a better response from one of them.

When my wood fires on 2 feet from me and its -40 outside my wws would melt so i put it in my cold room under my front step !1It likes cool better then hot lol find a cool place ( freezer ) lol hugs

Lately I have been using only one layer of Vilene. The company I order from claims that they usually only use one layer. It works for me. Today made 5 sets of the hearts charms from Yorikos site in a 8"x8" frame. I do use a frame cover made from rubber shelving material to make sure the material does not slip.

I have always been taught to use 2 layers of vilene wash away especially if using multiple designs in the same hoop. Hugs Joyce

Living in the neighboring state of Arkansas I find that I haven't had any problems so far. Knocking on wood as I type...lol. Might be that we are hot natured and tend to keep our home pretty cool.

Bev, I have never used badgemaster - so I don't know if the weather would do anything to it - but that does make sense as it is WSS - I remember one time - at the sewing center in NC - it has been a very humid day and the instruction had alot of WSS out for use in a project - I stayed to help put things away - we noticed that she had stored a large roll - right under the iron and ironing board - they also were using spray starch - that roll of WSS - had places that were stuck together - where the wet spray starch had landed on it - what a mess that was - but we managed to cut away the bad spots and store it in a air tight container and as far as I know - she never left her roll of WSS out like that again and it served to be a good lesson for me, as well.

I don't have any problems with badgmaster, and I live in the Houston, Texas area, very hot...I like it a lot but I do prefer vilene. Two layers is better but I always test the design with one layer and if it works I only use one...after all it is kind of expensive. On the badgmaster you don't fave to use two layers just good needles...****

I always use 2 layers of Vilene.

Hi Bev, I live in Colorado and had no problems with Badgemaster until I turned on the swamp cooler. Now it it limp as day old lettuce. I am lucky enough to have a sunroom with less humidity to stitch in. Live Laugh Download Stitch!

They do say that the Film type of water soluble stabilizer can be affected by high humidity and also dry climates.

In high humidity it can stretch.
In dry climates it can dry out and become brittle.

that is why they always say to store it in an air tight container or bag.

So for stitching on it I guess you need a cooler day or one with lower humidity.

The Fibrous type of water soluble such as Vilene water soluble is not affected by either.

Hi Bev, I use Badgemaster a lot. I do a lot of FSL and making badges and patches. Here in NW Arkansas humidity and heat are a problem. I have found that if I prepare my frame, cut the Badgemaster for the frame and immediately put the roll back in the plastic bag,then inside a box, it will last quite a while. I learned the hard way to not stretch it.
I use vilene, one to two layers for FSL projects that are a little more delicate.
Hugs for you, Bonnie
