I would blush too with a be-piped young man looking at my bottom.
-Mitt Pattern from Stitchcraft Magazine 1964
I've never encountered a motif constructed like these medallions are. They really highlight my doily top tip which is very hard to word.
When double or treble crochets are needed in isolation, or if a cluster is to be worked from a chain alone it is doubly important, when working the first stitch to raise the hook perpendicular to the work to ensure that each yarn over and loop is as high as the previous stitch or loop. It's akin to Lucy Neatby's Happy Stitches in knitting. If a stitch does not have a neighbour standing next to it, it is want to lean over or even flop. In crocheted motifs and doilies, this may make the excess thread pop out the bottom. Very unattractive.
You may need to estimate the height of the first step or stitch, but as long as you yank up your hook with each of the next loops or steps of the stitch, you will have a consistent and convincing look.
The hook perpendicular to the work brings the current stitch (in this case one leg in a cluster) level with both the previous stitches and the chain. The chain is pulled to it's full length to help determine the height of this stitch.
What I enjoyed the most about this pattern was Mrs. Crawford's bossy but charming finishing instructions:
"All joinings were done with needle and fine thread, the writer believing this to be the better method for many reasons."
Delish! Absolutely no justification! She also gives a collar top tip;
'Have a collar-pattern and, after placing the motifs as arranged, or in any preferred way, sew with fine stitches."
Aren't patterns from this era nice in their flexibility (the joinings bit notwithstanding). I like the room these instructions give for personal taste and creativity. I also admire this period's approach to garnitures; instructions seldom assume what you're going to use the pattern, or even the item for. Indeed:
