Some people definitely have put together similar premade sheets in the past. You're welcome to use them if you feel like it, but there are two things I want you to take into consideration:

• It is important that students go through all the exercises on a regular sort of rotation, ensuring that no major skills get left behind. I noticed that this sheet appears to do a good job of capturing the core of the lines and ellipses exercises, but doesn't appear to include anything for the boxes. While that's easily solved by simply having different sheets - so another one that does include box exercises - people do have a tendency of following things a bit blindly, without really thinking it through, and when they see premade sheets like this, some people will just shut off their brains and only do the one sheet.

• More importantly though, I find that there's a lot of value in actually going through the process of setting up a page to do an exercise just before doing it. It's a transitional experience that shifts us into the mindset of doing the exercise, of taking our time with it, and of generally approaching it with patience and discipline. When we work with premade sheets, we're actually putting ourselves in more of a mindset of getting through the work quickly, which can impact the way in which we practice the exercises themselves.
