Firstly, all of the yarns I used in this square, except one, were Patons 'Smoothie DK'.
The darker pink is Debbie Bliss 'Baby Cashmerino'. The light pink is colour 1092, from Patons. Also from Patons is the cream no. 1094, the mint no. 1095, and the green no.1010. The Debbie Bliss is a little thinner than a DK, but I'm just hoping I'll get away with it, in terms of it affecting the guage of the blanket as a whole, when the squares are sewn together . The Patons Smoothie DK is acrylic, but feels very soft, and has quite a nice sheen to it. At this stage, I haven't completed the blanket myself, so I'm not certain of the quantities of yarn needed, and I also don't know how many squares I'm going to have to do, mine is for a King size bed. Because these squares are quite big, it feels like less squares are needed!
ch = chain.
sl st = slip stitch
tr = treble
sp = space
4 ch. Join with sl st.
5 ch (count this 5 chain as 1 tr and 2 ch). "3 tr into ring, 2 ch" x three times. 2 tr into ring. Sl st into third of 5 chain. (You should have four groups of 3 tr).
Sl st into next sp. 7 ch (count this as 1 tr and 4 ch). 2 tr into same sp, 1 tr into each tr across one side of square. 2 tr into next sp. 4 ch. 2 tr into same sp, 1 tr into each tr across one side of square. 2 tr into next space. 4 ch. 2 tr into same sp, 1 tr into each tr across one side of square. 1 tr into same sp as 7 ch. Sl st into 3rd of 7 ch. (You should have 4 groups of 7 tr).
Change colour. Crochet as in round 2. (You should have 4 groups of 11 tr).
Change colour. Crochet as in round 2. (you should have 4 groups of 15 tr).
Change colour. Crochet as in round 2. (you should have 4 groups of 19 tr).
Change colour. Crochet as for round 2. (you should have 4 groups of 23 tr). Cast off. Sew in all your ends.
Now for the flower, which is done seperately, and then sewn on.
4 ch, (leaving a long tail to sew the flower to your crochet square). Join with sl st.
(2 ch, 4 tr into ring, sl st into ring) repeat instructions in brackets 3 more times, so you have four petals in total.
Change colour. Sl st into BACK of SECOND tr. Keep working into back of petals. With yarn at back, (4 ch. Sl st into back of 2nd tr of next petal), repeat instructions in brackets twice more. 4ch. Sl st into first sl st.
(1 sl st, 5 ch, 1 sl st) into each loop created by your 4 ch. Sl st into next sp. Cast off. Sew all the ends in, (except the long tail from the base ring). Then sew your flower onto middle of crochet square. You're done! Hurrah!
