Hi! Thank you so much for your feedback. Your easel looks great!
I understand that seeing parts come together on paper is not always quite the same as seeing them come together in real life, so that is why, in addition to the plans, I provide a step by step video of assembly so you can see how to put the pieces together (like clamping the stop block). This video is available on my YouTube channel, website and is also linked on page 1 of the plans. And if you ever have any questions during your project, I'm always available via email for help!
As a note, when choosing to modify the dimensions of one part of a project (like swapping 1x2s for 2' pieces), it's expected that other parts will likely have to be modified to accomodate those changes. Additionally, if you struggle driving pocket hole screws (in this or any project), by hand, you are welcome to use clamps. This article (linked on page 1 of the plans) shares more details on how to use pocket holes in your projects: https://www.woodshopdiaries.com/how-to-use-pocket-hole-jig/
