Free Square Crochet Coaster Pattern – Materials and Tools Needed

Yarn: I recommend using100% cotton, but this pattern will also work with 100% acrylic or a blend of cotton and acrylic. I also recommend using this yarn weight: Light Worsted #3 = DK but it will also work with Medium #4 = Worsted

 

I used 3 different colours to make 4 coasters (3 of each colour and one stripy coaster):

– Light Worsted #3 = DK

– 100% cotton

– 1x ball of khaki yarn – James C. Brett/It’s Pure Cotton – colour Khaki IC20 – (100g/215m)

– 1x ball of sage yarn – James C. Brett/It’s Pure Cotton – colour Sage IC16 – (100g/215m)

– 1x ball of beige yarn – James C. Brett/It’s Pure Cotton – colour Beige IC01 – (100g/215m)

 

Crochet hook: I used 4mm = G/6 but refer to the instructions on your yarn label if using different weight of yarn I recommend this crochet hook set that includes many crochet hook sizes but also yarn needles, stitch markers and other handy bits.

 

Tools used: scissors, yarn needle, measuring tape

You will crochet these coasters using the single crochet thermal stitch (SCTS), which means you will work single crochet stitches into two rows at the same time – the back loop of each stitch in the latest row and the front loop (unworked loop) of each stitch in the row below.

 

R1: Chain 21 – chain more if you would like a bigger size or less if you would like a smaller size coaster

 

R2: SC in back bump of each chain across starting from 2nd CH from the hook; CH1 and TO {20 excl CH1 at the end}

 

R3:

– start from the 2nd chain from the hook

– SCTS across in each of the 20 stitches following the steps below:

– SCTS = insert hook into the back loop only (Pic 1) and then the corresponding front loop (unworked loop) in the row below; in R3 the row below will be your starting chain so you will insert your hook into the unworked loop in the starting chain (Pic 2)

– yarn over and pull through the first two loops on the hook

– yarn over again and pull through the remaining two loops

– that’s your first SCTS completed; repeat for the next 19 stitches and watch out for the last stitch as it can be easily overlooked

– CH1 and TO {20 excl CH1 at the end}

Note: count your sitches at the end of each row to make sure you have the correct count

R4:

– start from the 2nd chain from the hook

– SCTS across in each of the 20 stitches following the steps below:

– SCTS = insert hook into the back loop only (Pic 3) and then the corresponding front loop (unworked loop) in the row below (Pic 4) and then SC just like you did in R3 (yarn over, pull through the first two loops, yarn over again and pull through the remaining two loops)

– repeat for the next 19 stitches and watch out as the stitch you have just completed can be easily mistaken for the next stitch

– CH1 and TO {20 excl CH1 at the end}

Note: don’t worry if your coaster is a bit twisted at this stage, it will flatten out as you crochet along

R5 – R34:

– start from the 2nd chain from the hook

– SCTS across in each of the 20 stitches

– CH1 and TO {20 excl CH1 at the end}

 

R35:

– start from the 2nd chain from the hook

– SCTS across in each of the 20 stitches BUT insert your hook through the whole stitch (both loops) in the latest row and then the corresponding front loop (unworked loop) in the row below

– do not CH1 and FO {20}

– weave the yarn ends in using a yarn needle

Note: Depending on your tension, you may need to crochet one row less or one row more to get a square shape. Make sure to use your measuring tape to ensure you have a square shape.

 

Colour changes for the stripy coaster:

R1 – R17: crochet in khaki colour

R18 – R27: crochet in sage colour

R28 – R35: crochet in beige colour

 

How to change colours:

– SCTS across in 19 stitches using one colour

– when working on the last SCTC: insert hook into the back loop of the stitch and the corresponding front loop (unworked loop) in the row below; yarn over; pull through the first two loops, then yarn over with new colour and pull the new colour through the remaining two loops on the hook (Pic 5)

– then CH1 using new colour (Pic 6) and TO

– continue to crochet the next row using the new colour

How to count rows when crocheting the single crochet thermal stitch:

– you can either count the visible rows or the worked rows – my pattern is written using worked rows

– worked row = every single row you will crochet

– visible row = two worked rows; because you will be crocheting into the latest row as well as the row below then two worked rows will blend into one visible row, i.e. one worked row will be hidden on the inside of your work
