My ComfyUI workflow that was used to create all example images with my model RedOlives: https://civitai.com/models/283810
The simplicity of this workflow is obvious: there is no clutter - and even the beginners can understand it very quickly! If you have issues with missing nodes - just use the ComfyUI manager to "install missing nodes".
P.S.: for use with SD1.5 you should switch not only the model but also the VAE in workflow ;)
Grab the workflow itself in the attachment to this article and have fun! Happy generating ...
