Check the above video for all the steps
I used this canvas print: Canvas design
Choose the type of wood, in this case i used 2x2x50 cm
Mark the wood using the picture, i used one milimeter more on each side of the wood, cut in a 45 degree angle.
Glue and staple all sides, front and back also
Reinforce the corners using the same process, gentle hamer the staples to have a smooth surface and let the glue dry.
Align the canvas to the frame, you will have an extra milimiters
Staple all the sides, streching the canvas everytime, the corners just need to be fold and stapled
And that´s it !
