shaping: sloped decresasing at the end of a row

This method works for stitches in the double or triple crochet family. 1. work the required number of rows without decreasing, Work one turing chain and turn your work.
2. Work a single crochet into the first stitch of the previous row.
3. Work a half double crochet into the second stitch of the previous row. (if you are working a fabric of half double crochet, continue working stitches across the row at this time).
4. Work a double crochet into the third stitch of the previous row. (if you are working a fobric of double crochet, continue working stitches across the row at this time).5. Work a triple crochet into the fourth stitch of the previous row. Continue working stitches across the row.
6. To decrease at the other end, work the starting stitches in the recerse order.
Hint: Shaping
If you need to increase at the same positon in subsequent rows, pllace a marker, such as a peice of contrasting yarn, at the position where your increasing begins.
To maintain a neat edge to your work, do not work an increase into the first of last stitches. Instead, use the second or second to last stitches.
The number of stiches used to create a slope will depend on the stitch you are working with. A row of half double crcochet will require one single crochet for the slope. A row of double crochet will require one single crochet and one half double crochet for the slope. A row of triple crochet will require one single crochet, one half double crochet, and on dourble crochet for the slope.
