so this website let's you:
tells you how accurately the seams will recreate the model when sewn
let's you designate fur direction
let's you import markings so the pattern shows exactly where they go on the piece
let's you add little measurements on the model that are also visible on the pattern
let's you paint the model to play with fabric colors
let's you name each piece so it's easy to sort the pieces later
let's you scale it beside a human
then calculates how much of each type of fabric you need, BASED ON YOUR DESIRED SEAM ALLOWANCE..
and finally gives you the finished pattern with the detailed names and instructions it's transcribed from your notes
this is. beyond. this is BEYOND. and as far as I can see it's free???
