WITUSE Wood Stretcher Bars Painting Canvas Wooden Frame for Gallery Wrap Oil Painting,Art Stretcher Bars,Canvas Mounting Kit-16"x20"

Began using this 10 minutes after it arrived. Works great. The adhesive pieces placed at the joints did not stick well but it does not affect the functioning of the stretcher.

Worked well but was a little hard to put together. Also the top is no longer sticky on mine but I had removed it and restuck it.

Easy to use. It was my first time and they worked great. I’ve now used them to mount 5 canvases.

It was easy to assemble but the adhesives came off with their protective covering so there was nothing for the canvas to stick to. It didnt stretch the canvas at all. Overall very useless buy. Had to buy a different one.

The plan for this frame is great. How, the "U" pins were glued together. I had to use glue remover to get them to a point where I could pry them apart. It was a very frustrating process and an average person would probably have returned the product or thrown it away. Also, I realize that the stretching bars need to be snug in the slots but the groove in the frame was so much smaller than bar that I had to use a hammer just to use them. Maybe a little bit better quality control.

The instructions were not as clear to understand. I had to watch a YouTube video in order to attach canvas to frame. The canvas did adhere to the frame but I wish it was a tighter stretch.

I mounted a 16x24 canvas easily on this frame before I began painting this picture. I added some thumbtacks because the picture canvas was not sized correctly. It was easy to maneuver while painting and now hangs on the wall, unframed in my condo. It was a great corona virus project.

Picture type directions needed and way to center picture on frame while face down. Using pin to make holes in corners while face up on frame, allowed me to center frame when picture flipped over. Make sure frame pieces fit together as one unit with corner pin type braces slightly in before assemble by removing tape from corners to press fit with glue on ends. Then put corner angle braces or stretchers in each corner. Important to make sure groove for these is down toward flat surface! Position frame, then pull off tape, only on side working, a short side and stretch picture boundary backward on to frame. Work it from center to edges alternating and pulling toward corner gently... Now do same for other end now stretching picture in center attaching to frame. Continue stretching picture on to frame alternating sides working toward corner. This stretching needs to also stretch toward corners to avoid wrinkles. Do same for longer sides, then trim corners, cut out square, so edges meet. Smooth out sides again wrapping edge over frame back and stable them.
