We are going to learn two different blending techniques:

- Erasing Technique
- Masking Technique

Before we start, I highly recommend you download my Circle Fuzzy Brush Pack for Gimp. Unfortunately, with Gimp 2.8, it didn’t come with this pack of fuzzy brushes like it did with Gimp 2.6. Please go on ahead and download them and install them into your brushes folder. If you are unsure how to download and install brushes, please refer to this tutorial. Now, let’s begin, shall we?

Here are the two images I’m using for this tutorial:

- GirlsGenerationasBrides.jpg
- 2PMinSuits.jpg

Save them however you like but just be sure to keep them in their .jpg format.

Also, move the 2PM picture to the top of the canvas, like this:

Now go back to the 2PM layer in the layers palette and right click on it again. Choose ‘Add Alpha Channel.’ You might want to go on ahead and add an alpha channel to the SNSD layer as well.

7. Now go to the toolbox and click on the eraser tool. Look down at the eraser palette which is right below the toolbox. Where it says Brush, their is an input box underneath it, click on i
