PreQuilt VS uMap

Prequilt does what you are asking, I think even the free version. https://prequilt.com. Source: about 1 year ago

PreQuilt is a desktop app with a subscription (you can pay it for a single month the one time if you want) that allows for this kind of design work. It’s not exactly cheap, but I saw it like a class or workshop on how to design my first quilting pattern. Without the app I would have had a much harder time, as the app can take into account seam allowance and fabric width (if I remember right), create blocks, etc. Source: over 1 year ago

For your dyscalculia, I'd use graph paper to see this. Or, I think something PreQuilt might be a huge help! Source: over 1 year ago

The pattern is a Ribbonpole quilt it's made using HST and was from this YouTube video I don't know what size the quilt in the tutorial is but I used the demo version of prequilt to size it down for a baby blanket and plan it out! Source: over 2 years ago

I haven't tried but I bet you could also import it into a uMap. Source: about 1 year ago

If you prefer not to use proprietary, walled-off services like Strava I recommend Umap which has some great map editing Functionality and allows sharing links or even exporting the maps as JSON. Source: over 1 year ago

I'm not hosting it myself but I'm using the open-source OSM uMap (https://umap.openstreetmap.fr/en/) with a custom layer that points to a GeoJSON endpoint on my webserver. Source: over 1 year ago

That being said, http://umap.openstreetmap.fr/en/ exists. This is a website where one can make a small map, personal or shared with friends who can edit. Source: over 1 year ago
