Somebody mentioned success with dissolving their wss scraps in water as a spray starch substitute but I can't remember who it was... I've seen recipes online that are just cornstarch and water so it shouldn't be too expensive to do a little test :-)

Yes you can make starch. There are a few recipes online. I would, except it is best to have a supersaturated solution and since I am at high altitude I would need a pressure cooker.

I would google making starch kind. But I have done the wss scraps dissolved in distilled water with alcohol I just put some scrapes couple tablespoons alcohol little more maybe and rest water. Works great I used it other day when I ironed on burlap placemat. Use it on fabric before putting in hoop a lot.

Both of the two ways posted should work. Someone did post about saving the tiny wss scraps and then adding water to it to use as a spray starch.
If you had ever done any crocheting and wanted something really stiff, you would mix up corn starch and water and dip it and then dry - so this would easily work. You would have to experiment to see what quantities work for what you want.

What will you be starching? Your embroidery or everyday clothes?

i bought some at Walmart heres what it looks like now incase you missed it!!I still iron pillow cases as i like them crisp lol

I like the wss and distilled water too. I mix only the amount I am going to be using cause I have seen it spoil* You can make it thick or thin to your preference .

I don't use spray starch. I use spray sizing. The starch can leave fabric shinny the sizing doesn't. Just another idea for you to consider. Hugs, Susan

Hey, Loralye, did you figure out which starch was best to use? How did it work out? There were so many good ideas here, be sort of interesting which one worked best for the quilt fabric you're using. I'm going to be making some quilted wall hangings, so I have a personal stake in this answer, hee hee hee. Anybody know if you're going to use fusible applique if it's wise to starch or not? My hangings use all fusible, so that's important. Thanks for letting me (us) know the results, hugs, Marji

Yes, I make my own spray starch all the time. Get a bottle (at the grocery story) of liquid starch, depending on size of your spray bottle. Pour liquid starch in the spray bottle, fill the rest of the way with water. If item you are ironing isn't stiff enough, add more liquid starch.

You can make it as thick as will come out of the nozzle.

Hope this helps,
