Half Granny Stripe Blanket

The Half Granny Stripe Blanket pattern is a variation of the traditional Granny Stripe (or Granny Stitch Blanket ). The traditional Granny Stripe involves creating rows of treble crochet (UK terms, this is a double crochet in US terms) stitches worked as clusters (a group of three treble crochet stitches) into the spaces between the clusters of the previous row.

The result is a series of horizontal stripes that gradually build up, which can look stunning in different colours, and is completely reversible. The pattern is loved for its simplicity, making it perfect for crocheters of all skill levels.

Half Granny Stripe Blanket

This Half Granny Stripe Blanket tweaks this traditional pattern and uses rows of half-treble crochet stitches (this is a half-double in US terms) worked in clusters of two stitches instead.

The result is that it maintains all the appeal of a traditional Granny Stripe, but using the slightly smaller stitches means that the work has smaller holes and the work has a beautiful drape.

Colour Palette

The colour palette for this project was inspired by some beautiful and bright spring colours. I have written a short blog post on this. The colour range from soft pinks, through the mauves and purples to the blues and turquoises.

Notes on the pattern

This is a really simple pattern, based on a 2 row repeat. The pattern uses the half-treble crochet (this is in UK terms, in US this is the half-double crochet stitch) worked in groups of 2 (htr clusters) and is a variation of the traditional Granny Stripe, which is usually worked in groups of three treble crochet stitches.

As with the Granny Stripe this Half Granny Stripe pattern is suitable for beginners.

The foundation row made up of double crochet (in US this is single crochet), which helps to provide a more solid foundation for the first row of half-treble clusters to be worked in, than working directly into the foundation chain.

Working in stripes and changing colour

The Half Granny Stripe Blanket looks wonderful worked in stripes. This blanket is worked in stripes made up of 3 rows of each colour. This means changing colours on either side.

To change colour for a new stripe you can use any number of methods. I like to introduce the new colour before the ‘yarn over’ of the last stitch of the previous row. I have suggested this method in the pattern below. Alternatively, any other method of changing yarn colours can be used.

Written Pattern for the Half Granny Stripe Blanket

Start with Bluebell yarn.

Foundation Chain – Chain 160. Multiples of 2 plus 2 for turning.

Foundation Row – 1dc into 2nd ch and then in each ch along. Turn.  [159 stitches]

Row 1 – Turn. Ch2 (counts as a stitch), *skip 1st, 2htr into next st,* repeat from * until 2 stitches remain, skip 1st, 1htr into last st. Turn. [78 htr clusters plus 1 htr at each end]

From row 2 and subsequent rows the htr clusters will be worked in the spaces between the htr clusters from the row below.

Row 2 – Ch2, 2htr in first space (the first space is between the single htr worked at the end of row 1 and the 2htr), 2htr in each space until the last space (in between the 2htr and turning chain from the row below), insert 3htr in this last space. Turn. [79 htr clusters plus 1 htr at each end]

Row 3 – Ch2, 2htr in 1st space (you will be stretching over the first three htr from the row below) and in each space until 1 space remains, 1htr in the last space. Fasten off Bluebell colour (Note: you can before introduce yarn colour Spearmint for the second colour stripe before working the final yarn over of the final stitch.) Turn. [78 htr clusters plus 1 htr at each end]

Subsequent Rows: repeat rows 2 and 3, changing yarn to a new colour every 3 rows. Note that as this pattern is worked in stripes consisting of 3 rows of each colour, this means that you will alternating the end that you will need to be changing colour.

Complete a total of 70 stripes (each stripe made up of 3 rows). This is the equivalent to a total of 210 of rows of the Half Granny Stripe stitch.

Colour Order

The colour order is listed below. Remember that there are 3 rows of each colour.


Half Granny Stripe Blanket

The edging is a really simple border worked all in one colour over 3 rounds. It is important that you create an even base to work the border stitches into. For this project the base round is a round of htr clusters. The border is simply 2 rounds on this base round – the first is a round of half treble stitches worked in between the stitches of the round below. The final round is a round of double crochet.

The base round should create an even base. You may want to work this round more loosely or more tightly, depending on your tension. You may wish to change hook size. You may also want to adjust the number of stitches down the sides of the blanket and work the stitches more/less frequently to ensure the blanket lays flat and does not ruffle. Similarly you may feel that you need to adjust the number of chains in the corners to ensure the corners lay flat and even.

The border is all in Lapis colour as I felt that a slightly darker colour framed the colourful blanket nicely.

Border base round (WS): Using Lapis yarn. After fastening off the last row (row 210 in Bluebell), turn the work over (this will be the wrong side). Pull up Lapis yarn in the space between the first and second stitch in the top right corner.

Chain 2 (counts as 1htr), work 1htr in the same space. Skip the next 2 stitches and work 2htr in the next space between the htr clusters, continue working along the top of the blanket with 2htr in each space.

When you reach the end of the row, work 2htr in the space between last stitch and final htr cluster. Ch1 and work 2htr in the same space.

Now work down the left side of the blanket, continuing with htr clusters. Work these htr clusters around the post of the last stitch. Work these at the end of alternate rows. You may find that you need to keep these stitches loose, or alternatively you may want to do the htr clusters more or less frequently to ensure that your work does not curl of ruffle.

When you reach the row of double crochet worked at the start of the blanket, work [2htr, ch1, 2htr] in the end dc stitch to form a corner. Along the bottom edge of the blanket work 2htr in the same double crochet stitches where the first row of htr clusters were worked. Upon reaching the end of the bottom row, work [2htr, ch1, 2htr] in the last stitch to form a corner. Work up the right hand side of the blanket, working 2htr at the end of alternate rows.

In the corner space where you started the round, work [2htr, ch1] and ss into the top of the beg-ch2 to close the round. Do not fasten off. Turn over.

Border round 1 (RS): Slip stitch back into the ch1 space just formed. Ch2 (counts as 1htr), 1htr in same space. Work 1htr in between each of the stitches of the round below along the first side, [2htr, ch1, 2htr] in the corner space. Continue around the sides of the blanket with 1htr in between each of the stitches of the round below and with [2htr, ch1, 2htr] in each corner space until you reach the start of the round. [2htr, ch1] in the corner space where you started the round. Ss into the beg-ch2 to close the round. Do not fasten off. Do not turn.

Border round 2 (RS): Ch2 (counts as 1dc). Work 1dc in each stitch around the blanket. Working [1dc, ch2, 1dc] in each corner space. Upon reaching the corner where the round was started, work [1dc, ch2], ss into beg-ch2 to close the round.

Weave in all ends.
