Here's a fun pack, something a bit different. You've probably all seen the doodles on sites like instagram, Visothkakvei does some exceelent examples, well this pack allows you to do the same thing in Affinity Designer but lets you concentrate on the design by including over 300 pre-made objects. You can also scale, rotate and flip them to provide even more variations. Just copy and paste them from the template to your work (or use Alt drag). I tended to use 3 layers background, middle and top but there's no right way.
You can stick to a monochrome theme, more like an inked doodle, or use fills and gradients for a more colourful look. Fun for all the family!
There are a few examples in this thread on the Affinity forum
