If you remember
@Flobear I showed you the two or three larger cones that are poly, the rest are rayon which doesnt melt under usual circumstances.
Good cotton fabric, double the stabiliser, dont over tighten the hoop and RAYON thread is best!
Id say you did a jolly good job with both of those designs! Brava!
Basting stitch is added after you press embroider on the screen a lil flower in a hoop shows up in the icons on screen HOWEVER this is where you can sometimes get the error message change to a larger hoop as the basting outline has extended the size of the design too much.
I would then just delete the basting stitch if you dont want to rehoop or waste stabiliser.
