I have a friend who often laments that she can't grow anything, bemoaning the fact that she can't decorate her house with any houseplants, especially disgruntled as now it seems to be making a comeback! I didn't think I'd see the day that my mum's macrame plant hangers would be on trend!
So I crocheted some cacti for her using some hand spun wool that seemed to be a good "cacti" colour, a combination of merino, alpaca and silk.
I "potted" up a couple of cacti for her and with a few cacti left over I potted up some for me too. They are now sitting on my work desk, a little bit of colour, with the added bonus that they don't need any watering!
I didn't have a pattern, but I did google "crocheted cacti" for a bit of inspiration, there are some amazing examples. If crochet isn't your thing, have a look at these painted stones! I think the kids and I might have a go at those these holidays.
