Triangle of Fine Checked Gingham, 6 Inches on Straight Sides. Cord 6 Inches.
Cotton, No. 80-100.
Trimming for underclothing or dolls' clothes.
This exercise is to show the uniting and hemming of bias pieces, and also the economizing of material in the utilization of a triangle.
Take a triangle of checked gingham the straight sides of which are six inches. Fold back the triangle so it comes one-half an inch below the base and cut through the fold. Cut the base into two equal parts. A bias piece may then be joined with a fine running stitch to each side of the triangle, matching the pattern if there is any. Allow the apex of the triangle to extend as far beyond the seams as the matching of the pattern will allow. A narrow hem should be made on the bottom of the bias strip thus formed. The top may be turned over a cord and a casing run in, being careful not to catch any stitch in the cord. Draw the ruffle up and put a knot in each end of the cord so it will not slip through the casing. If a ruffle is to be placed on a garment, that will take the place of practice.
Every effort should be made to have classes understand the relation of the gain in length to the loss in width in the bias. It is well to have problems presented which will deal with the purchase of material and the calculations of amounts required for different sized bands or ruffles. For instance, how much bias velvet, twenty inches wide, would it require for bands four inches deep to be placed on a skirt three yards around? Let the children who are making the bias ruffle on the petticoat (see suggestions under garment bias) decide how much it would take for this little skirt, compare straight with bias ruffles, and also let them cut paper on the bias to represent the amount of material. They should see the difference it makes if the triangles at either end cut from the straight material are utilized. The classes can utilize the ruffle for trimming dolls' clothing or for larger garments. Practice is not necessary unless the pupils are very inexperienced.
