how would you spend it?
I would buy some underglaze colours that I’ve wanted for a long time and maybe stock up on some clay. I would also look at investing in stocking my work on maybe one more selling platform.
I know that £500 doesn’t really go far these days!
I was going to replace my gazebo this summer - yes that’s how much a professional one costs! Instead I’ve decided to rent from the fair organiser. It’s more expensive in the long run, but easier on the cash-flow. Also I don’t have to put it up and take it down 
I keep thinking about having rubber stamps made of my drawings. Maybe one day.
A soft box lighting rig for year round properly lit photo taking but since I haven’t got space for it (and £500 doesn’t buy me the end of next doors garden and put a new work shed on it) I’ve got my eye on some fordite on eBay - £500 might cover it.
A new laptop,this one not going to live much longer!
Some Advertising also
Hmmm, there are so many ‘things’ I need! I would possibly invest in advertising…actually FABRIC 
A new sewing machine that I’ve had my eye on for a while now. That would take £400-and-a-bit. The rest I would spend on fabric (because that’s what I do!! )
Ohhhh I would love to stock up with lots of new Polymer Clay, it’s getting so expensive.
Would be nice to have a desk just for my crafts with fab storage around it.
** starts to daydream… **
A graphic’s pad 
A proper polisher (I keep having to take my jewellery mops to work and using the one there - the benefit of teaching D&T) and I’d love a small rolling mill too
Marketing materials and a new craft table.
Some lovely marketing material, a rivet press and fabric. There are so many fabulous types of material on the market I just can’t afford to try at the moment.
OOO happy dream! Register my hallmark and get some pieces hallmarked. Get the workman in to finish my workroom, some boxes I can’t move need putting in the loft and racking installing, which would mean I can have my lounge back. Finally buying some more gift boxes, sterling chain and wire.
I thought that I would revive this thread as I have been daydreaming about having some investment over the last Month!
At this moment in time, I would like to pay an electrician to wire in my pugmill (that I have had sitting there doing nothing since February!) - this would mean that I could easily reclaim the tens of bags of broken bits of clay and I could save money having to buy more stock! I also need some more glaze materials desperately, so I would buy those too.
@thedotterypotter that is an interesting name ‘pugmill’ 
I would have my floor redone in my studio, I laid a light vinly floor when I moved in as that is all I could afford, it is wearing down and tearing in places, so I would love to lay a gorgeous wooden floor.
A bigger saw for slabbing stuff (electric with air extraction to keep dust down please) and space to put it. I think I might have gone a bit over budget.
Ooh so many things! Tools - some kind of polishing tool / machine so I don’t keep polishing my fingertips, or a blow torch (& training to use it!). Or just general jewellery making courses as I do feel like I’m making it up as I go along! Or looking again at registering for hallmarking & working in silver. Or improvements to my ‘workshop’ (back bedroom!) such as a decent desk & chair so I don’t keep ruining my back. Oh it’s nice to dream…
@SashaGarrett actually an extractor fan would be a great thing for me too, and a better hoover! and @OrukiDesign a small enamelling kiln as I have been thinking of enamelling silver for a while… to go with my glass … too many things…
What a great question, I must have missed it first time around!
I’d probably upgrade my sewing machine. Or maybe try having my own fabrics printed.
I’d consider actually spending some on marketing because it’s not something I normally do (well obviously I do what I can for free, but it’s not something I like to spend money on).
Oooh, or a nice new printer that works with thicker card than my current one does.
