So, I’ll admit, I kinda dropped the ball on updating this week. No excuses, though, so here it comes. All the updates from the past week. One right after the other.

First up, the Set-In Sleeve block. This pattern is going to be made to fit, and thus will be based on, the Basic Bodice Block you made in the previous post.

You will need paper, a pencil, a ruler, and a french curve.

Because the original measurements are metric, and their US standard equivalents would be near impossible to accurately measure (1/5 of an inch?), I’m going to stick with the metric measurements.

* ** *** ** *

**Step 1: Trace on the top** of the bodice block, from the base of the armscye, up. You can do this either by copying the shape to a new large piece of paper or cardboard, or by using a tracing paper overlay. Be sure to include the point labels; you’ll be needing them a lot.

**Step 2: Extend Point T** vertically so that it passes through point Y, touching the edge of the armscye.

**Step 3: Mark the point** above point T one third of the *total* armscye measurement, not the half armscye measurement we were using before on the main bodice. Label this point AC.

**Step 4: Draw a new line** horizontally at the level of point Y, midway between points T and AC.

**Step 5: Mark the point** where the line from Y crosses the left-most edge of the armscye curve. Label that point AD.

**Step 6: Mark the point** halfway between points T and Y. Label that point AE. Draw a very short horizontal line across to the ARMSCYE curve and mark the intersection. Label that point AF.

**Step 7: Measure the length** of the ARMSCYE curve between point AF and point X at the top – not the length of the straight line connecting points AF and X, but the distance ALONG the curve. To do this, drape a small piece of string along the curve and then measure the length of the string when it is straightened out.

Now, add 1 cm to this (for bust sizes 94cm-107cm, add 1.25cm. For bust sizes above 107cm, add 1.5cm.) Zero the ruler at AF, and pivot the ruler until this length meets the horizontal line at AC. Mark the point at the intersection point AG.

**Step 8: Measure the distance again** along the curve between the point AD and Point I at the top of the left part of the armscye curve.

Add 1cm to this distance (1.25cm for bust sizes 94-107cm, 1.5cm for bust sizes larger than 107cm.) Zero the ruler at point AF, and pivot the ruler until the intersection with the horizontal line at the Y level corresponds to the length just calculated. Label this point AH.

**Step 9: Measure the distance** from Z to AF along the curve. Subtract 0.3cm. Zero the ruler at point AE, and pivot the ruler until the intersection with the horizontal line that passes through point T corresponds to the length just calculated. Label this point AI.

**Step 10: Measure the distance** from AD to Z along the curve. Subtract 0.3cm. Zero the ruler at point AH, and pivot the ruler until the intersection with the horizontal line that passes through points T and Z corresponds to the length just calculated. Label this point AJ.

**Step 11: Drop a line vertically** from the summit point AG. This line will be the length of the sleeve measurement, taken from the top of the shoulder to the wrist. Mark the end point AK.

**Step 12: At this point in construction** the basic bodice you traced earlier is no longer needed. Go ahead and erase any of the unused lines and points. They won’t be shown in any of the diagrams beyond this point, just to keep things clear and easy to follow.

**Step 13: Drop a vertical line** from points AI to the horizontal line passing through point AK. Mark this new point AL. Drop another vertical line from point AJ to the same horizontal line. Mark this new point AM. Draw a new horizontal line from AL to AM.

**Step 14: Draw in a curve** from AI to AH, hollowed below the diagonal by a maximum of 0.75cm.

**Step 15: Continue the curve** above the line from AH to AG, raised 1 cm at maximum deviation. Make sure that the curve flattens to the horizontal as it passes through point AG.

**Step 16: Continue the curve** downwards to point AE, passing 2 cm at maximum deviation above the line connecting AG and AE.

**Step 17: Finish the curve** of the sleeve head, dropping it below the line connecting AE and AI by 1 cm at maximum deviation, and making sure it approaches the horizontal at point AI. Note that the sleeve head shape is asymmetrical – this is as it should be.

**Step 18: If you wish** to introduce some shaping into the sleeve, you may narrow the sleeve by a distance of from 1 to 3 cm on each side. This is completely optional. If you do, mark your new points AN (1-3cm in from point AL) and AO (1-3cm in from point AM)

**Step 19: Lower the sleeve edge curve** by 1 cm on the section between AN and AK (the back section of the sleeve). Raise the sleeve edge curve by 1cm on the section between AK and AO (the front section of the sleeve).

*If you chose to skip the shaping, replace “AN” with “AL” and “AO” with “AM”

**Step 20: **This is the final outline of the sleeve. The waist line on the bodice block marks the location of the elbow on the sleeve.

Ta-Da! You’re done! Enjoy the endless possibilities your new personalised sloper will bring!
