Do you or your children want to draw on your clothes and textiles? For example, to cover stains? Or just for fun :)
With these markers, you can draw on various types of textiles. Iron them afterwards to make them permanent. After ironing, they can withstand washing up to 60 degrees Celsius. On the test swatches, I have used all the colours in the 12-pack so you can see what they look like. In the last picture, you can see drawings that are drawn relatively similarly, on polyester and on cotton, and then one has been washed and one has not been washed at 40 degrees. So far, they have only been washed once, but with a very good result.
As you can see, the colour "bleeds" a lot on the polyester satin. Make sure to test the colours on the fabric you are going to draw on, or on a similar fabric, before you start, to find out if it works, and also what kind of motif works on the fabric you want to draw on. You can draw on fabrics where the colour bleeds, if it is a more abstract, watercolour-like motif; the most important thing is to allow yourself to test and play with the colours on different textiles.
The markers I used for drawing on the test swatches have 2.0mm tips.
