A little side note I forgot to mention in the video: If you press all the pieces for a bag, make sure you switch around your pieces and press them on different sections on your pressing board, so the board doesn't get too hot and start melting your vinyl from the front.
I recommend going to youtube to watch this video.
It'll give you better quality then the embedded version.
I'm still very much a youtube beginner so any helpful hints or comments are much appreciated!
And I'd love if you become a subscriber of my channel! That way you won't miss any upcoming sewing tips or tutorials: http://www.youtube.com/c/PinkPonyDesign
