Experimenting DIY silkscreen printing

It was a little hard to set up DIY silkscreen printing in house. Especially exposing a screen with opaque ink in the Sun needs testing. I did it in several ways four times; the Sun expose and Eye lamp (for photograph) expose,  but it was not successful. Fortunately there is a printmaking studio in which open to the public near my house, I have exposed my screens using the machine for 40 seconds and that seemed to work well. A madam, seems almost professional, she adviced me to how to do it. I feel grateful for her help.
