I'm a sewer and use PDF patterns via Adobe, the sewing world has now caught up with tech now and we are projecting our patterns via our projectors. I have quite a few patterns from a certain company where the outline of the pattern is hard to see. I have pulled a pattern through affinity (very new to this software) and edited last night (made the lines thicker to see and colour coded all the pieces on the pattern) but today I've tried the same pattern and adjusted to a different size (grandchildren different ages) so I can do the same as above but when I go to export it tells me it cannot be exported....I have tried other patterns and it seems they are all following and giving me problems exporting them....any advise please.
