About the pattern
This is a pattern I was asked to write for my mother to knit. She lives by the sea, and loves all the colours of the sea. She picked a yarn that looks just like the colour of a shallow, sandy bay in a certain kind of weather. She asked for cables, a tree of life and lots of moss stitch in the top half, and a different texture in the bottom half. She also thought a raglan with a little saddle would be nice. She likes her jumpers nice and loose so she can wear layers underneath. And despite having knitted for 80 years, since knitting socks for the Forces during WW2 at Primary school, she has only ever knitted one jumper in the round. It’s never too late to learn! However, we drew the line at top-down, for which I am grateful, as I think this pattern is much more fun to knit from the bottom up.
The tree of life motif is found in many cultures with many variations, but this knit and purl version is often found in fishing Ganseys from coastal communities around the British Isles. It can also be found in colourwork and lace knitting. The cable is a simple 3-strand plait. The motifs are separated by a vertical line of twisted knit stitches.
The jumper is knitted from the bottom up in the round. Lower body and sleeves are worked separately and then joined in the round to form the raglan yoke. Neck shaping is made with back and forth rows, and shoulder saddles are formed with short rows. There are various options for the neckband. The picture shows a folded neckband. There is minimal finishing.

Skill Level
Adventurous intermediate. Techniques include casting on, binding off, knit, purl, simple cables, grafting (which can be avoided if necessary), simple increases and decreases, picking up stitches, and short rows. Motifs are worked from a chart or written instructions as preferred.

Finished measurements (after blocking)
Finished bust/chest circumference 85.5[95, 106.5, 116, 125.5] {137, 146.5, 156, 167.5} cm 33.75[37.5, 42, 45.75, 49.5] {54, 57.75, 61.5, 66} in.
This garment is designed to be worn with 10-15cm/4-6 inches of positive ease at the bust. Pick a size that is about 10-15cm or 4-6 inches above your actual bust size.
The photos show size 3 (medium) worn with approx 10cm/4 inches of ease.

Yarn
The photo shows John Arbon Yarnadelic Worsted in colourway Woman in Blue. This is 100% Falkland Corriedale wool, spun in Devon. It has three plies and is bouncy and soft. 216 metres/236 yds per 100g skein. 5[6, 7, 7, 8] {9, 9, 10, 11} skeins.
And in metres and yards: 1057[1194, 1312, 1447, 1561] {1748, 1895, 2083, 2243} metres 1155[1304, 1433, 1581, 1705] {1909, 2070, 2276, 2450} yards.
For yarn substitutions, it is important to use a yarn that gives good stitch definition. Choose yarn with a smooth, round profile, ideally 3 plies or more, and a solid or only slightly heathered colour. A heavy DK or light aran yarn would be suitable if you can work to the correct gauge.

Gauge
21 sts and 31 rounds to 10 cm/4 in over pattern used for lower half of body. I achieved this using 4mm (US6) needles.

Needles and Notions
Long circular needle in size needed to achieve gauge. I used 4mm (US6).
Long circular needle 0.75mm smaller for working hem trim. I used 3.25mm (US3).
Needles in both sizes suitable for working smaller circumferences in the round: double pointed needles, short circular or magic loop as you prefer.
Cable needle of your preferred type.
Stitch markers, at least 4, for marking start of round and raglan shaping points, more if you want to mark patterns on yoke (recommended).
Stitch holders or waste yarn, for holding sts at centre front neck and underarms.
Tapestry needle for sewing in ends
