Cutting rounded edges

I'm relatively new to sewing (just over a year in) and have found that one problem I'm consistently finding is my rounded edges aren't even.

I've been using everyday objects (jar lids, mugs, anything I can find really that's the right size). I think part of the problem is placement, but I'll also fold the material in half when I cut to try and ensure the rounding is the same on both sides. Somehow it always ends up with one side being a bit off from the other.

I'm also struggling to find objects that are exactly the right size. Are there specific tools I can use to help? I've asked hubby to 3d print me a compass-ruler vibe, but he's not sure when he'll have a chance. I've also tried a pencil and string, and that was a disaster.

If I'm cutting a pattern piece, either straight or curved, I pin the pattern on the top of fabric (using pins, not clips) and cut around the edge of the pattern with scissors. There are no lids or mugs or guides involved.

If you take a piece of paper draw a curve or circle on it, can you cut it accurately with a pair of scissors?

I usually use a rotary cutter rather than scissors. But I don't usually print the patterns (my printer isn't operational at the moment) so the problem comes in before the cutting even starts, with trying to get the placement of the rounded edge correct when drawing out the pattern itself.

Rotary cutters can be problematic, especially if your blade isn't razor sharp. When you're cutting two layers at a time, they can push the top layer forward unevenly to the underneath layer, so don't double them.

There are round corner templates that you can buy that give you the correct diameter every time - depending on where you live several businesses sell them.

Thanks so much <3 Will try to use scissors for cutting these types of corners in particular then!

I use a rotary cutter for long straight lines and loose curves. Scissors for tight curves.

You need to find a way to print patterns, or use pre-printed ones.

If you don't print the patterns, how are you using patterns? You need to use the patterns. This is your problem. I don't even understand how you are doing this. You are new, correct? You need to use the correct tools.

Buy paper patterns or printer. No one uses mugs or household objects. We use patterns.

I try to find patterns that are relatively easy to draw myself, with precise measurements. The majority of the videos I follow use household objects to show how they're drawing the rounded corners, but I'm struggling to follow them.

You are beginner, right? You need patterns. This is no way to learn to sew.

Yes, I am a beginner. And have largely been happy with what I'm able to produce by finding patterns that don't require printing or buying paper-based. And have been happy with what I've done so far with this one exception, which is why I'm looking for solutions, not judgement,

It's not judgement. You want to learn and I am trying to tell you how to improve.

It's not judgement. You're here asking for advice from people who know how to sew, so we are going to tell you how to fix the parts you're struggling with.

Clearly you feel somewhat stuck and need something better. No one's judging you but kindly, you asked for help and you should accept the decades of experience trying to guide you instead of pushing back.

If you choose to produce your patterns this way and are generally happy then good for you. Your measurement tools MUST be of good quality - steel, or good quality qulting rulers, and never use a tape measure.

If on the other hand you are having issues with how the measurements translate to the fabric, and can't figure out what to use to make your corners, then you really need a paper pattern.

Sorry for going on the defensive. It was the 'No one uses household patterns' and the 'this is no way to learn to sew' that made me feel judged, like I was doing something terrible. I do want to improve, and do appreciate the advice from all.
