Onto a Frame

Material

» Stretcher bar
» Canvas
» Hammer
» Staple gun with 3/8 inch staples
» Measuring tape or a T-square
Procedure

✤ Take four stretcher bars (two of the same size) that will make a frame. Cut them into the size of the frame that you need to make.

✤ Lay the stretcher bars on the ground and the corners towards each other.

✤ Use a rubber hammer to fix them together, make sure that you don't dent the bars.
✤ Now stretch the canvas and place it on the ground. Make sure that it is minimum two inches bigger than the wooden frame.

✤ It should be stretched from the longer side of the frame as it will help in fixing easily.
Use pliers for stretching as they will prevent tearing of any intensity.
✤ Always make sure to staple the it at the back of the wooden frame.

✤ Use as many staples as you need, beginners take more staples than the experts. You need to be very cautious at the side of the frame.

✤ Fold the corner edges neatly over each other and fix them.

Stretching a Canvas Painting

Mostly when a painting is sold, it is delivered as a big roll which is hard to stretch.

Here are some tips you might want to follow to stretch it without damaging it.

♠ Measure the sides of the painting (length and width) and then buy the wooden stretcher bars which are 2 inch smaller as you need to wrap its corners onto the frame.
♠ Create the wooden frame using the above-described procedure and put it over the painted canvas (placed on the ground as painted side down). Fold the edges over the frame and use a stapler for fixing.
It is always useful if you try to do this with a little help of a friend. Your friend will help you hold the canvas while you fix it to the wooden frame with the staples.
