Calling all designers out there! Craft Stamper are currently looking for designs for our free covermount stamp. Do you think you could design a stamp that will appeal to a broad range of mixed media stampers? Now is your chance! We are looking for designs for our September, October, November and December 2019 issues, so any kind of image you feel will represent that time of year. The finished design must be one single image, black and white, 5cm by 5cm in size and sent to us as an Illustrator file (.ai) Please remember, it has to be YOUR OWN WORK only, we will not accept images that breach copyright rules. No copying or tracing images from the internet, please. The successful designers will be invited to contribute projects using their stamps to the magazine, and will be paid for these projects at our regular designer rate. We would love to see any and all submissions as soon as they are ready, with a cut off date of February 19th. Please send over your designs for consideration to Craft Stamper editor Trish at editor.cs@mytimemedia.com. This is also the email address for any questions!
