Crochet Edged Coaster Tutorial

We have been working on this pretty crochet edging project for one of our workshops. Crochet edging can be used on anything from coasters (which we will make today) to clothes. We have four different styles of edging for you to choose from.


To make 4 coasters you will need:

  • 2.5mm hook
  • 4ply cotton
  • large eye tapestry needle
  • For every coaster you’ll need two squares of fabric 20 x 20cm;
  • A 20 x 20cm square of ‘Heat n’ Bond’ Lite;
  • A tailors awl or other sharp pointy object to puncture holes.

Stitches used (patterns use UK terms):

  • Chain (ch)
  • Double crochet (dc)
  • Treble crochet (tr)
  • Slip Stitch (ss)

A note on tension! If the edging is looking too loose and is not laying flat, try using a smaller hook.

Preparing the Fabric Base

To make the base of the coasters, we’re using a 20 x 20cm sample of upholstery fabric. You can use any type of fabric you like, but firm cottons fabrics are ideal. You’ll also need a thinner backing fabric and a square of ‘Heat n’ Bond’ or similar iron-on adhesive.

Following the instructions on the Heat n’ Bond, fuse the two layers of fabric together. This has the advantage of stopping the coasters from fraying and gives the fabrics a thicker more sturdy feel.

Once you’ve fused together the fabric squares, either use scissors or a rotary cutter to neaten the edges and cut the large square into four 10 x 10 cm squares.

Turn the coaster over and on the back using a heat erasable pen (we use Fixion pens from Pilot) mark lines 1cm from the edge. Then with a ruler, mark along the lines at 1cm intervals.

Next, placing the coaster onto a chopping board or similar (otherwise, trust me, you make a neat set of holes in your table!) and use a tailors awl to make holes at each of your marks. When you’ve made all the holes, carefully either use an iron or a hair drier to erase the pen.

Blanket Stitch

The next step is to use the holes you’ve just created to work a round of blanket stitch around the coaster. Take care at the corners to make sure they are neat, following as in the photograph below.

Once you’ve worked all the way around the coaster with blanket stitch it should look like this. Cut off the yarn and tie ends then weave in at the back of the coaster.

Round 1 for all designs

Each of the four designs starts with a round of double crochet.

  • Join your yarn to the blanket stitch running along the edge of your work, work 1 ch (which counts as your first double crochet);

Loop under the blanket stitch and attach the yarn to start crocheting.

  • 3dc in each blanket stitch space along the edges
  • For each corner make 4dc in each side of the corner, allowing extra stitches will help the corners to lay flat.
  • To finish, join with a slip stitch into the initial 1 ch.

Your coaster should then look like this.P1030092

Chain Loop Edging

Round 2

Work Round 1 in double crochet, as detailed above.

  • *Ch 5, skip 2 dc from below, dc in next space* repeat from * to * until reaching the corner. At the corner work 6 ch and skip 3 DC twice. Then continue to work from * to * until the corners, where you work 6 ch and skip 3 DC twice as above.
  • Repeat all the way round, to finish join with a slip stitch into the 1st chain.

Shell Edging

As with all the coasters, work round 1 in DC as detailed above.

Round 2

Each shell ‘cluster’ takes up 2 blanket stitch sections, so make sure that you start an odd number of blanket stitch spaces away from a corner.

  • Make 1 ch, and dc in the same space
  • *Skip 2, Make 7 tr in next dc from Round 1, Skip 2, dc in next*
  • Repeat from * to * for the straight edges;

For the corners: Skip 3dc from Round 1, then make 11tr in the next dc, skip 3, dc in next. This will create the fan like shape all the way round the corner.

Granny Edging 


Simple granny edging is very pretty.

Round 2

As with all the coasters, the first round is worked into the blanket stitches in double crochet, as detailed above.

  • 3ch, this counts as your first treble, make 2 more tr into same space, skip 2 dc
  • *3tr, skip 2 dc*
  • Repeat from *to* until reaching a corner.
  • Corners! – make 3tr in the 4th dc of corner, 2ch, then 3 tr in first dc of next side.

Finish the round with a slip stitch into 3rd of your initial 3 chain.

Round 3

On this round you continue to work 3 treble clusters into the treble spaces you created in round two.

  • 3ch, this counts as your first treble, turn your work so that you now have the back of the coaster facing you and make 2 more tr into tr space from Round 2.
  • 3tr into next tr space – repeat to corner
  • Corners! – make 3 tr into chain space from Round 1, ch 2, then 3 more treble into same chain space.

 Picot Edging


Picot edging would be perfect for lots of projects.

As with all the coasters, the first round is worked into the blanket stitches in double crochet, as detailed above.

  • 1 Chain (counts as your first DC), 1DC into next 2 DC from round 1. *3Ch, 3DC* repeat from * to * until corner.
  • At corner, work 4DC , 3 CH, 4 DC then revert to working from * to * until next corner.
