How can i stretch my UV map? I'm trying to stretch my uvs so they fit within the texture, however, I can't find a way to do it... i can only resize my uvs
i could stretch them manually but I'm trying to find an easier way

This is what I'm getting after resizing the image and re-importing it to blender

This is what i want to achieve by stretching my uvs, i just don't know how .
( yes I'm quite new to blender )
In the header of the uv editor you can set the pivot point to your 2d cursor and then place it on one of the right vertices; scaling on the x axis should give you the stretch effect you're looking for
