After the disappointment with my first attempt, I’ve triumphed! (Visit my previous post so you know what I’m talking about.) I had another go this week with this trousers idea, making them roomier. They now have the perfect degree of pajama pant bagginess.
UPDATE 13th March 2020: This pattern now has a new improved gusset which is easier to sew and has no stress point at the apex. It’s been graded to a range of sizes too. View it here.
By all means feel free to adjust the amount of ease to suit yourself. Note that the crotch depth is dependent on the ankle width and hip circumference; if you change one thing it will change the gusset size (fascinating, isn’t it?).
If the crotch depth is in the wrong place, adjust it from the top by making the waist casing bigger or smaller, or even separate.
This pattern may or may not fit neatly on your fabric depending on the fabric’s width. If your fabric is a little too wide, you could just take bigger side seams and take advantage of the selvedges for the sides.
Allow bigger side seams if you want the freedom to adjust the amount of ease.
