Buying a properly pre-stretched screen. With stapling your mesh is probably going to be loose which wont help with coating or printing. They arent super expensive. We sell them, as well as Amazon/ ebay https://www.amazon.com/Aluminum-Screen-Printing-Screens-Pre-Stretched/dp/B07RB84R9F/ref=sr_1_12?dchild=1&keywords=screen+printing+screens&qid=1602267713&sr=8-12
$50 for a trim bin was a little too pricey for me, i used- Aluminum Screen Printing Screens, Size 10 x 14 Inch Pre-Stretched Silk Screen Frame (110 White Mesh) https://www.amazon.com/dp/B07RB84R9F/ref=cm_sw_r_apan_glt_fabc_T1MMRRQKG47SMKM7V6EM?_encoding=UTF8&psc=1
Mine may also have been cheaper because they’re smaller but they’re perfect for me here in Pa where ounces are between 250-600 silk sceens
here ya go I got the 110 one because I’m going for the best quality, but I heard the 150 works just as well
done! just make sure you get the 110 micron
