My experiments with ironing knitted swatches of plastic yarn (plarn) showed that they lost their elasticity. So I thought I could use this to advantage by ironing some crocheted coasters.
The photo below shows a crocheted circle before ironing. It’s a bit difficult to see, but the different types of plastic make the texture quite uneven, and the coaster doesn’t sit quite flat.
The photo below shows the coaster after ironing – interestingly, it doesn’t shrink very much.
And below is a collection of coasters in different colours. Again, the various plastics all behave slightly differently, leading to varying sizes and irregularities in texture, but I think this is part of their charm.
