Sorry, a very novice question .ive never had a business so I dont know how the forms look or what I need to know but I'm keeping all invoices etc just incase....

I've been making jewellery as a hobby and also for gifts for family and friends but I have also been making a small collection too.

I have been buying sheet silver and just designing off this but I have a lot of scraps which I don't believe I will ever use.

When filling out Self assessments, is there a way to get relief from wastage of silver, ie buying a sheet of silver, making a couple of pieces but the rest is unusable.
I am worried I loose out buying bulk silver to make a piece and half of it ends up scrap, I don't want to over charge on a piece to recoup scraps, especially if it's not a custom order.

...I'm hoping this makes sense...
