Caseados 

“As in the case of the cordão stitch, from which it must have arisen, the caseado stitch is done over a thread lain down twice. But the second time the needle passes over the thread to be pulled and produces an effect called lançada whereby, on being tightened creates a strong edge and enables the adjacent cloth to be trimmed without undoing the stitch.” It is normally used for finishing off the extremities of embroidered pieces. There is the other option of the caseado bastido, which is fuller, and the undulating “unhas” instead of the straight line.
