Hi, I hope someone here can help me! I've been searching online to find a fix to this problem, but I've only seen solutions for Illustrator, not Photoshop Elements. I'm using PSE 2020. When I Define Pattern as a single block and then choose Fill Layer to multiply the pattern onto a larger canvas, faint white seam lines continuously appear. I can zoom in and they are still there (a bug mentioned in Illustrator), I can't find where I can see if the pattern has shrunk or added a decimal to the pixel size or canvas size. How can I solve this issue without having to painstakingly go over my final canvas with a blur or pattern stamp?
Thanks for your help!!
Can you post a sample pattern before any editing was done to it?
I don't see any issues with the two sample patterns you provied.
I reduced the size using Image>Resize>Image Size to 512px x 512px before going to Edit>Define Pattern as below and still don't see any seams. I used a new document of 8.5 x 11 for the images below.
