And there was a very emotional goodbye...

This week's Sewing Bee featured the six remaining sewers trying not to get their knickers in a twist (we got that one from Gill!) as the series slipped seamlessly into lingerie and sleepwear week.

The quarter finals are just a week away, so the heat was on for the contestants who had to work hard to impress judges Esme Young and Patrick Grant to make it through.

Last week saw Angela leaving the competition and Annie winning her first Garment of the Week with her beautifully sewn double-breasted Bowie-inspired blazer.

The first pattern challenge was the fiddliest yet as the sewers were tasked with creating a bra and matching pair of lace knickers.

Patrick insisted that Esme was the underwear expert and that he "knew very little about it", prompting Esme to get cheeky (no pun intended!) and correct him, quipping: "I think you do actually!"

The pattern construction of the knickers sees the gusset inserted first, with the sides sewn up and the elastic added to the legs.

For the bra, the lace front and side cups are lined with power mesh, then sewn together with the top edge to form the bra cups. They’re then attached to the underband, which is inserted with the underwire. Elastic is then sewn onto the bra edges, the straps are added and the bra is finished at the back with a hook and eye tape.

Annie was on a winning streak and had “two on the bounce", as Patrick put it, when she triumphed in the pattern challenge with her very elegant white lace bra and matching knickers.

Unfortunately, Gill's bra was a little bit wonky in the centre despite almost top marks for her neatly sewn knickers, placing her last, followed by Cristian, whose red knickers were not symmetrical.

Debra's fabric was described as "tres chic" by Esme, but a lumpy gusset put her in fourth place.

Brogan's wearable pink pair saw her come in third, with Man Yee in second with her neatly sewn navy blue underwear set.

It was on to the transformation challenge and the sewers had to turn thermal sleep sets into a garment for going out in. Patrick wanted to see the contestants turn their items from "Nana to Rihanna".

Gill's asymmetrical boob tube with a sleeve and gathered skirt was deemed underwhelming, with a trim which was a "touch of too much of a Disney princess", according to Patrick, placing her last.

Although the judges liked Man Yee's imaginative lattice bodice, they weren't so keen on the daisy embellishments, which placed her fifth. Next up was Brogan with her pink frilled dress, which Patrick thought was "a little too House on the Prairie", so she came fourth.

In third place was Cristian with his tiered daisy dress, and Annie was in second with her plaited halter neck top made from a pair of leggings.

In first place was Debra with her grey and primrose sweater featuring frill details and two statement bows. Debra received two coveted c-words for her creation; it didn't just get a "chic", it was also likened to a Chanel design.

Gill and Cristian had to step it up for the final Made to Measure challenge, as they found themselves in the bottom two. The sewers had to create a pair of luxury pyjamas for men. The fabric choice was crucial - cotton is easier to sew but silk, which is slippery and far trickier, is the more luxe material.

Borgan's cotton palm leaf pyjamas were well sewn, but the judges agreed they looked more like a beach co-ord than sleepwear.

Esme loved the paisley fabric Annie used for her long sleeved pyjamas and shorts, and Gill was complimented on her Chinese style pyjamas featuring a round neck and vibrant orange piping and matching drawstring. Cristian's paisley pjs looked luxury, but the sleeves were a little too long for Esme's liking.

Debra wowed once again with her polka dot print pyjamas with burgundy buttons, smart collar and "fabulous" burgundy piping.

But it was Man Yee's understated blue and red pyjamas with a bee insignia that were described as the "height of luxury" and a "knockout" by the judges, which saw her winning Garment of the Week. Well done Man Yee!

Sadly, it was time to say goodbye to Gill, who's heartfelt leaving speech led to tears in the sewing room.

Gill, your sewing is phenomenal and you've been such an integral part of the sewing room. We're so pleased to have played a tiny part in your journey and can't wait to see what you accomplish next. #SewingBee pic.twitter.com/Lu9oUtAraw

"It's been life-changing for me in a completely unexpected way," she said. "Before coming into this I would always wear a prosthetic limb, and I have done for the whole of my life, and coming into this, I knew that I wouldn't be able to do that.

"It's kind of made me realise that I don't need to do that anymore, so you've kind of like set me free. On a whole different level. So thank you."
