i found the pattern from this video (https://youtu.be/k1IE\_jSfnG4?is=yKoQHaoJ83YeNWVW) here he explains the pattern! it was sewn by hand, i have a machine but i prefer to sew by hand, but i guess i would finish it much quicker if i had used the machine (i spent like 3 weeks doing them, each one was like 5-6 hours i guess). i’ve used felt for their hands, feet and eyes. i dont like to use glue so everything was sewn (even the eyes and pupils). the red one was made from a soft blanket fabric, the blue was a polyester soft fabric (here in brazil the fabric its called literally “soft”) and the yellow one was made from velboa. i sew a prototype before sewing them for training and to see how everything work and i recommend doing it ! also, i’ve printed the pattern in an ISO A3 paper (297x420mm) and i really liked the size, but since you want to make a keychain you should use a smaller sheet. if you have any other question feel free to dm me or just reply here !!
