I put these two face to face (dye side in) and sprayed both sides with soda ash water
I threw them in a plastic bag and the next morning popped it in my Dye Only microwave for 30 seconds. The next day I did the ones below.
* The video showed applying dye with a credit card. The fabric was untreated so I sprayed the back of the fabric with soda ash water then put the first two pieces face to face in a plastic bag and microwaved for a few minutes. The other pieces were wrapped in plastic and batched for a few hours with warm rice bags on them. The edges of the images were not blurred probably because the soda ash was sprayed on the back of the fabric.
