Hello there,
  I just found out about your site. I was so amaze with your brief and clear instruction. I am new to the field, I am learning from many videos on Youtube from different people . I just have these questions for you: 
1) When We use Decorative stitches on the sewing machine. Do we use regular thread or need to use Embroidery Thread ?
2) Do I need to put anything over the decorative stitch, for my paint hem to last longer after many wash in the washing machine ?
3) Can you tell me when do we use Tear away and when do we use the  Wash away Stabilizer ? 
Thank you so much
