Choose fabrics that can count as threads when embroidering.
Make sure the length and width of the fabric are exactly square.
Make sure the tip of the needle you use is blunt (use a cross stitch needle)
Determine by counting the place on the fabric according to the squares of the pattern to be embroidered.
For the cross stitch, choose muline thread. Separate the threads and process in 3 or 4 layers (depending on the size of the pattern)
Do not tie knots when starting to embroider, leave 2-3 cm of thread extension, then collect the thread at the bottom
