I considered that, but didn't want to have users see that the default is way bigger / smaller than their measurement, especially since my target audience people who can't find patterns that fit their particular sizes.. any suggestions?

I could put in better error handling to avoid measurements that are physically impossible

That's true, maybe a range input would work though (slider control) it would be nice from a usability point of view.

If people can quickly go through the steps and see a preview, I don't think they'll be Ashamed of the default sizes, but I'm not the target audience I guess...

Yeah, getting people to the last step more quickly would be ideal, maybe a slider is the way to go. thanks!

Thanks!!! If you feel comfortable with it , feel free to send me the measurements that you used so I can try to troubleshoot the problem! (or email me at easysloper@gmail.com)

I was contorting with a tape measure and typing them in, so my apologies I can't. :)

Haha no problem. I should probably add something in to send me measurements that don't work anyway

I created this myself!

It's very neat, although there are some errors if you type in a number too large, the error text covers the input box and you aren't able to change your measurement.

Ah good feedback, thanks!!! Are you using a desktop or are you looking on your phone or something?

Slopers are like a 'second skin', which are the basis for making more custom fitting patterns (https://www.mybluprint.com/project/the-sloper-is-your-secret...)

The only other ways I've seen of making one involve taking a bunch of measurements and doing a bunch of geometry, so this is my attempt at automating that!

Let me know what you think!
