Hi I'm in the middle of making my first ever self patterned plushie too! Do you have any resources or tips? I have no idea where to look for help.
absolutely!! im still learning new things along the way but i'm more than happy to share what i know!
these are the only two things ive learned on my own so far, but they're definitely handy to keep in mind nonetheless
don't expect your first try to come out pitch perfect! when it comes to patterning, 99% of the time there will be some parts that need changing and it may take more than one upgrade to finally get it the way you want it to.
put small guides on your patterns! where the opening for turning the plushie right side out with be, placement arrows that will help match where certain parts go, seam allowance amount, etc. this will help you out a lot in the long run! i used to ignore the given guides on free patterns but once i started paying attention to them, i felt my creations improve a bit. don't forget to label pattern parts!
for tut's these pages have always been my biggest go-to's for help;
i've learned 99% of what i know about patterning and plushie making from both of these sites there are a big part of the reason i've gotten to where i am today. they have a lot of useful guides, from patterning to sewing and whatnot.
best of luck on your plushie making journey! <33
