Sending work for Assesment

   Today I sent off my work for Assessment.
I am quite worried that I have not done everything correctly.
 I realise that I have foolishly signed most of my work and cannot remove it. My tutor brought this to my attention in his feedback for Assignment 5 but by then the damage was done. I somehow missed the instruction not to sign work along the way. I will know now not to do this in the future.
 I have also worked too much on loose pieces of paper and sticking them into a sketchbook doubles the weight of my parcel. I need to change the way I do this for my next course and work far more directly in sketchbooks.
 I also could not buy the right kind of portfolio in a large enough size and the one that I have is quite floppy and bendy, I hope it survives the post.
