Before sewing I like to tie both ends / tails firmly to make sure no end unravels.Roll the rose into shape and pin to hold. Thread one tail through the tapestry needle and sew through the layers of the rose. Do so with the other one.
Leaf pattern
Ch 10. Starting from 2nd ch from hook, hdc1, dc1, dc1, tr1, dc1,dc1, hdc1, sc1 1 (one side made) next repeat the pattern in reverse for the other side: sc1, hdc1, dc1,dc1, tr1, dc1,dc1, hdc1, sl st. Chain 1o more and repeat the leaf pattern for the second leaf.
Bead pattern
Assembly / sewing
First sew the roses over the leaves and then onto the beads you want them on. Decorate with pearls.
Arrange the buttons – the bigger in the center, the smaller at the sides. I crocheted the circles – instead you can use felt or fabric to cover the back.
If you want to make crocheted patches, ch5 and join to make a ring. sc2 in all. Work this increasing pattern for a couple of rounds. If it is a big button, after those couple of increasing rounds, work sc1 in one st, sc2 in the next until you get the desired size for your button. Sew the buttons together.
To make the necklace chain more secure I started chaining from the second button from the last, then secured that one too. I ended the chain with a small leaf. When you are done with the chain, ch3 more and in first of those 3 chains, dc3, ch 3 and sl st into the 1st st. Sl st in next, pull tail, tie a knot and weave it through the leaf. Do so with the other side.
I hope you get inspired to make something similar yourself!
