Most garments can be embroidered. The only thing we can't embroider are socks, shoes, some laptop bags and fabric CD cases .
Basically, we can't embroider through fabric that has cardboard inside, as we need to frame the garment.
Leather & Organza:
We can embroider leather/organza materials, but no responsibility taken if the needle pulls the leather/organza apart, best always to bring a fabric sample before embroidering the actual garment.
Ties:
We can embroider most ties, but sometimes the embroidery may move due to the way ties are made, but this doesn't happen very often.
