STEP 1 Print 2 photos in the darkroom that you would like to weave together. At least one must be a portrait.
STEP 2 Think about how you would like to weave the two images together. There are examples above for inspiration, you can also look online for more ideas if you would like. Have a plan before you start.
STEP 3 Begin slicing one of your images using an x-acto knife and ruler. You may want to measure your slices. These slices will be woven into your other photo.
STEP 4 Begin slicing your second image. How you do this will depend on what you want the final results to be. Everyone will not be doing the same thing. You may be cutting slits, they may be all the same size, they may vary, they may be over the entire photo, they may only be in sections. Consider creating a design.... Be creative, think.
