You may remember my “I have a new obsession” post. Well since then I have been working on more celtic designs, in particular I have continued thinking about how to make a coaster.
I had given up the crochet cotton coaster because my hands were hurting but it occured to me that it might be possible to make one in DK weight yarn if I gave up the idea of combining five pieces, so I tried with three and my standard method of working out how many chains were needed.I realised that although this worked well for my celtic bookmark that the gaps in the resulting coaster would be better eliminated, so I reduced the number of trebles (US-dcs) for a crossing point from four to three and tried again.
I had realised that using less trebles per crossing, I could increase the number of pieces from three to four.
Now, I had shown you how I messed around with a drawing program to see how different colours could be used. I had a play and chose to make a couple more coasters like this from my regular stash.andI then thought it might be fun to use just two colours arranged so as to get a chequer pattern in the centre.
This is what you get.This four piece coaster is the one for which I have written out the pattern but of course using the basic idea of three stitches for a crossing point and five into one for a corner you could design any number of pieces plaitwork coaster you chose.
I thought that starting each piece with the three chain and then just one stitch before the first corner worked well.
Now the pattern – UK terms – if you are in the US just replace treble (tr) with double crochet (dc).
Celtic Coaster pattern
These are very easy to make. The trickiest bit is fitting the four parts together.
You make two each of two different shapes. There is a long thin shape and a rectangular shape.
I used DK (US light worsted weight) yarn and a 4mm hook. You need to have a fairly firm strip, so use a different hook if necessary depending on the way you crochet. I crochet fairly tightly.
Mine came out about 3.5 inches square (9 cm).
Long thin shape
Start with 42 chain. (It is quite a good idea, if you are not too much of a perfectionist, to chain a few extra and then remove them at the end, just in case you miss the odd one.)
Ideally you want to work into the loop at the back of the chain (my method four in this post – https://rainbowjunkiecorner.wordpress.com/2015/06/25/four-ways-to-crochet-into-a-chain/ )
This gives an identical edge to both sides of the strip.
Treble into fourth chain from hook, then 5 trs into each of the next two stitches, tr into each of the next 18 stitches, then 5 trs into each of the next two stitches, tr into each of the next 16 stitches.
This ensures that the join can be behind another of the pieces.
Starting with 42 chain and working into the back loop again.
Treble into fourth chain from hook, then 5 trs into next stitch, tr into each of the next 6 stitches, 5 trs into next stitch, tr into each of the next 12 stitches, 5 trs into next stitch, tr into each of the next 6 stitches, 5 trs into next stitch, tr into each of the next 10 stitches.
Join the ends of one of the long thin shapes.
I find that it is better not to join the other ends until you are sure you have got them interleaved correctly.
The best way I find is to position the long thin joined shape and then interleave the similar shape as shown below.You then add one of the rectangular shapes going over and under as shown in the photograph.or use this diagram.The stars represent the joins. The black ones show when they are visible and the arrows show where they are when hidden under other layers.
As the original diagram showed the two thinner shapes are the ones to interleave first. They must go under and over exactly as shown. Join the ends.
Then you add one of the other two going under or over as shown. This will hide one of the joins.
When you add the last shape all the joins will be hidden. This time every under will be followed by an over.
Check that each piece alternates between going over and going under and that all the joins will be on the underside.
When you are satisfied, join the remaining three pieces, press, and your coaster is finished.
