Ah right......well thats no problem.
For future ref you can remove parts of a LAYER in one of two ways....destructively and non-destructively.
What you have done so far is DESTRUCTIVE. This means that once you erase or snip away those pixels they are gone for good.....never to be seen again.
The non-destructive way is to use a Mask....or more specifically a 'Layer Mask'.
You apply a 'mask' to a layer by clicking the 'Add a Mask' icon at the bottom of the layers panel...3rd icon from left.
It will initially appear totally White, indicating that the pixels on that layer are visible....but, if you PAINT, in BLACK, with the brush tool on that Mask those pixels will become transparent.
You can use all the regular tools you would normally to create a 'greyscale' mask, to represent the visibility of the pixels within that layer.
Why bother with all this?
If you make a mistake you can simply paint pixels back in by using White....or any 'Greyscale' value.
The advantages of this go without say really.....and is just the thing you need for this.
Add a mask to the 'pig' image.
Make sure the MASK is SELECTED (Not the layer thumbnail !!! )....whichever is selected will have four white corners around it.
Now, grab that brush, check that the colour is balck and start painting along those seams.
You'll notice the 'pig' image being removed to reveal the seams underneath.....but in reality you are just 'hiding' or 'masking' the image from view.......paint over it again in white and it'll be restored to the 'pig' image again.
Pretty simple really.
You can do all your 'erasing', 'deleting' and 'snipping' like this safe in the knowledge that if you make a boo-boo then its cool......just switch colours and go back.....no worries.
Just remember to have the MASK selected BEFORE painting.....its easy to forget....and you dont want to paint over your pixel layer.
So....BLACK hides the pixels, WHITE reveals the pixels and any shade of grey in-between will add transparency depending on the shade of grey.
You may, in this case, find it easier to completely fill the mask with BLACK and paint in WHITE instead.....it'll mean you can see what you are doing....especially at the seam edges.
One other tip.....if you need a straight line when painting just click, hold down shift and click again....instant straight line between the two click points......good for straight seams.
