hmm did you learn to hand sew or use the machine? machine-sewing is a little easier imo and i would recommend getting extra bobbins/thread for it! also buying denim and universal needles 4 ur machine is great. for sewing by hand, make sure you know how to do different types of stiches (like stiches for garments vs ones for embroidery). lots of different sized needles and standard black/white cotton thread is good too! a thimble is helpful but i personally dont like it. a seam ripper, safety pins, regular pins, and sewing scissors are very helpful as well. if ur doing garment work, i also recomment a soft measuring tape for precision :3
i mostly do embroidery and some machine work but i hope this helps!! xx
