We asked about stuff to reuse/recycle as homemade soup moulds not too long ago but Danell has messaged with a variation on that theme:

I want to melt old crayon stubs together to make new crayons for kids. I know I could use old muffin tins or ice cube trays, neither of which I have, but I was wanting them in a little more interesting shapes. I’ve seen them made in candy molds, but again, I don’t have any. Any ideas?

A lot of the soup mould ideas we had resulted in practical rather than interesting shapes – but I’m sure there are interesting shaped potential moulds out there too :) I’d look to kid-related packaging – sweet (candy) packaging or toy packaging which is formed plastic around a shape. With Easter coming up, there might be a few egg or bunny shapes floating around for reuse.

Another idea might be to make your own moulds: I suspect Danell doesn’t have all the time in the world for carving intricate shapes but — and this is a complete I-have-no-knowledge-about-this suggestion — could they be made from something like salt dough? Could you make a sheet of salt dough in a baking tray and press fun shapes into it – again toys or magnetic letters – then varnish it to use as a mould? Please feel free to correct me if that wouldn’t work!

One thing to remember – there needs to be a balance between interesting shapes and usability. I’ve seen some new crayons made in star shaped moulds but I imagine the pointy bits would hurt small hands and be a bit awkward to hold too.

Any other ideas? What have you used for interesting shaped moulds — whether for crayons, soap or sweets? Have you made your own moulds from anything in particular?

Someone on my Twitter feed yesterday – I can’t remember who, sorry – asking about ways to recycle or reuse the material from vertical track blinds.

My first – instinctive – reaction was “bleugh!” because I hate the feel of those blinds ;) My second thought was “good question!”

We had lots of great ideas for re-using the slats from Venetian blinds so what about vertical blinds?

The fabric is usually synthetic and a little rigid & scratchy (hence the bleugh!) so not ideal sewing material but I’m sure those attributes could be strengths in some projects. The strips of fabric are usually about 10cm/4inches wide and as long as the window drop (so typically at least a metre or so).

On the slat blinds post, chez suggested using vertical blinds to make a shopping bag — weaving the strips together. They could also be woven together to make a protective mat – or even a picnic blanket type thing if you’re not so phobic of the fabric as me :)

Have you reused or upcycled vertical blinds in any way? What would you do with the material?

We covered old leftover paint on the site many, many moons ago (roughly 66-67 moons ago apparently) but these last few weeks, we’ve been rather overrun with little tester pots of paint here.

I hate tester pots from an environmental point of view – usually plastic pots, sometimes with an integral brush, that are thrown away once their purpose has been served – but I’ve made enough costly paint mistakes in the past (and in the very recent past, she says knowing there is £80 worth of unsuitable-for-current-job paint sat upstairs…) to begrudgingly accept using them.

I think there are two questions here: how can I use up the little bits of paint? And second, is there anything I can do with the little pots?

The amount of paint in each tester is only enough for very small projects. I remember at uni painting a set of drawers with leftover tester pot paint – each drawer a different shade of blue – and the sides of the pots themselves tell me they’re suitable for stencilling, where you just need a little paint of each colour. Have you done (or seen) any mini-craft projects using leftover tester pot emulsion paint?

As for the pots themselves, the ones I have here tell me they’re polypropylene – plastic number 5 – which can be recycled but isn’t collected everywhere yet. The pots seal very tightly – as you’d expect from something containing paint – and so they could be washed out & reused for containing other liquid things or keeping other things dry or safe. I won’t use them for anything food related – since they’ve contained paint and aren’t food grade – and probably not anything like plant seeds either — but they’d be fine for small amounts of non-edibles/growables: like old film canisters, they’d be useful for all sorts of little fishing related things, for beads or buttons, and nuts/bolts/screws or sewing needles etc.

What would you reuse them for?

Long time Recycle This friend (and very frequent commenter!) Anna has a question about the protective sleeves slipped around wine bottles:

Any ideas what to do with the plastic nets they put for wine bottles for protecting them when you buy one?

I don’t drink wine so I had to turn to my friend Google to see what those nets are like – some have big holes and look foamy, whereas others have smaller holes and look more like the thin plastic netting you get garlic bulbs in (a smaller version of orange/onion nets). I think the former are to provide some “bounce” protection while the latter just keep all the big bits of glass together in the event of a breakage. (Please correct me if I’m wrong about those assumptions.)

Either way, the first suggestion has to be reduce if you can: if they only add the netting at the shop after you’ve bought the wine, don’t let them: either take an old net to reuse or throw caution to the wind and just go nude ;)

As for reusing them for other things, the thinner/smaller holed nets can be filled with bird seed to make your own bird feeders, filled with the ends of old soap bars and hung on an outside tap for garden clean-up, or bunched up to make washing scrubbies.

I’d be tempted to throw a few of the foam type ones in with our reusable shopping bag stash for when we go to the supermarket for a big shop – they could cushion glass jars and other glass bottles to save them clinking together all the way home. Opened out flat, the foam ones would also be useful as cushioning under heavy plant pots (so they’re less likely to damage/dint the surface they’re stood on) or between occasionally use crockery to save that knocking together too.

How do you reuse or recycle those nets?

It’s seed-starting time here in the northern hemisphere and my Twitter feed is full of exciting stories about what fruit & veg people are going to be growing this year. I’ve added half a dozen more fruit bushes to our garden this year but I’ve not sown any seeds yet — my seed box is sat on the side of my desk making sad puppy eyes at me as I type ;)

Gardeners & allotmenteers are just about always resourceful types when it comes to reusing and recycling stuff – I don’t think I’ve ever met a grower who doesn’t keep ice cream/margarine tubs etc for reuse – but I thought it would be worth having a bit of a sharing session about what you reuse for starting seeds, as plant pots or as water-catchers under plant pots, and if there is anything that you choose not to reuse for whatever reason.

At one point, a good few years ago now, I think about 90% of my seeds were started in plastic mushroom tubs — either directly in the tub or using them to catch water draining from plants pots. In the past, I also used shallow fresh pasta packaging as starter trays and multi-serving yoghurt/cream pots for the growing on stage. I know my dad keeps the clear plastic boxes used by supermarkets for muffins or pastries whenever he gets them because the lid gives the tray its own little propagator/greenhouse too – and similarly he cuts down 2ltr pop/soda bottles to make a pot with its own little cloche.

Moving away from plastic – since I do worry about putting plastic in direct sunlight/warm spots when it’s not designed to be used in that way, I’ve used newspaper and toilet roll tubes to make “plantable” pots – the former just require a little folding into shape and the latter can be cut in half to make twice the number or left whole as “root trainers” for growing carrots or parsnips.

(I also cut up plastic milk bottles & drinks cans to make plant markers for all these many, many seeds!)

So, what packaging (or other household waste) do you reuse for starting off your seedlings? What about for the growing on stage?
