Perfect as a tree decoration using oddments, or for leaving little seaonal yarnbombs around your town
For the pictures I used an Aran weight (worsted/10ply) dark green yarn and a 5mm hook, but changing the yarn weight and hook size will determine the size. ie if you would like REALLY small ones using 4ply and a 2.5 hook, for larger use a bulky yarn and a 7mm or larger hook. You may also need to add or remove a DC or so at stage 3 to get a neat round wreath.
American terms used, for UK use Treble Crochet instead of DCs at stage 2 and 3
1. Chain 4, slip stitch into 1st chain to make a circle, chain 2
2. work a double crochet into the middle of the circle
3. Work a further 19 DC into the circle (total 20DC and the 2 chain)
4. Slip stitch into the top of the1st DC ... sew ends in neatly at back
5. Cut a length of contrast yarn for bow, knot around one of the DC make a bow, pull the bow loops to size and neaten.
Double knot the bow again to secure firmer if wished. Cut a length of contrast yarn for hanging (about 20cm), hold yarn in center and feed through top edge opposite the bow, pull both ends through loop and pull tight to create a hitch knot
6. either leave hanging loop ends open to tie to tree or knot ends together to create a loop. Further decorate with some glue and glitter or sequins if desired for that snowy/iced effect
