Crocheting double crochet stitches

Dear users, dear authors,
Would you like to share something about crocheting double crochet stitches?

Basically, half double crochet, double crochet, treble crochet, and post double crochet are probably familiar.
Double crochets are actually suitable for almost everything. I think they're ideal for all kinds of filet crochet. I like crossed double crochets for shawls/sweaters.

Especially for thick yarn, I've discovered the boho double crochet for myself. With it, you have three loops on the hook (as with a regular double crochet). Then you pull the yarn through the first loop and then through all three loops. Of course, you can also crochet this with any other yarn.

For a color change in crocheted pieces worked in the round, the standing beginning double crochet is an alternative to the chain foundation, which unfortunately always remains quite visible. For the standing beginning double crochet, you put the slip knot and a yarn over on the hook. Then you insert the hook through both loops of a double crochet and pull the yarn through. You work these three loops -as usual- in two sets of two loops. The standing beginning double crochet is finished.

For straight pieces too (and grannies), the standing beginning double crochets (also called false double crochets) are an alternative to the three turning chains, which don't make the edge look very nice. Here you pull the loop up to about the height of a double crochet, hold it in place with your thumb, then go behind the loop with the hook and bring the yarn to the front. That gives you two loops, which are then worked together. The edge looks much more even.

I hope I've explained this clearly. You can find good explanatory videos on the well-known platforms.
