The web site says to use a Top-stitch 90/14 needle. What type of needle are you using?
I like Micr-Tex 80/12 for most projects and threads.
What stitch are you using for the applique? I like the one that looks like the edge of a leaf. Adjust the width/length
of the stitch depending on the design.
A thread stand should be used with metallic threads. Perhaps a thread net will help also. Don’t give up on the embroidery yet.Your
project sounds cute.
