Work great for machine embroidery esp on cork or pleather products!
Unfortunately I haven't had a chance to use these yet and I have never used a microtex needle before but I will say the Organ brand is top notch!
I use these on my embroidery machine for felt, vinyl and basically everything. They last much longer than regular needles. My very favorite!
I needed these for the first t-shirt quilt I made. Ellen recommend this for maying quilts
