I crocheted these in one hour one night for my youngest girl. I'm yet to work out how to make them the right size for the other girls or for myself.
You will need to know how to crochet a bobble stitch or treble two together, which will be notated as treb2tog in this pattern. Treb2tog is creates by starting a treble stitch, but then doing a treble half way through. That is, yarn over, insert hook in to stitch, yarn over, pull through 2 loops, yarn over, insert into stitch, yarn over, pull through 2 stitches, yarn over, pull through three loops. Pictoral instructions are available here.
Using 8ply yarn and a 5.0mm hook, chain 4. Slst into first chain.
Chain 3, double stitch into circle formed – this creates the first treb2tog. Treb2tog a further 11 times.
Chain 3, double stitch into first gap, treb2tog into same gap.
Treb2tog twice into each gap.
*Ch3, treb into each stitch**. You should have 24 treble stitches.
Turn. Repeat from * to ** once.
#Ch3, treb into 16 stitches ##
Turn. Repeat from # to ## at least 5 times, until slipper is required length.
+Treb into 3rd stitch, then treb into each st until 3 from the end. Slst into final stitch++. This creates the heel of the slipper.
Repeat + to ++ until the top of the heel is even with the edge of the sides of the slipper.
Tie off neatly.
Repeat the whole thing for the second slipper.
