If you use a metallic thread, use a larger needle size, and one with a large eye if you have a needle like that. Slow down the machine too!
I have done 7 different snowflakes and only one needs some help. I am letting them dry hope to post pictures tomorrow.
first one I made I forgot about the bobbin thread having to be the same colour as top thread.
I started on the pretty snowflakes also. I don't normally do FSL either, because they didn't always turn out very well. This time I used a sharp needle, heavyweight ultra solvy (bought at JoAnn fabrics) and Maderia thread....mine turned out beautiful and are drying now!
I usually use 2 layers of Vilene type WSS (not the plastic looking one) and a 7/11 needle. After embroidery is completed I leave it in a bowl of warm water just long enough for the excess to wash away, blot it dry between paper towels, lay it on a flat surface and let it dry. Have fun.
this is how I do mine and they turn out great!
Trim any threads before rinsing. I love FSL designs. I hope you have great success. Merry Christmas.
