I love these shorts, but they are just a tad bit short on my 7 year old girls. I am making the size 6 which fits them well with button style elastic. I don't think we could move up to the size 7, but in order for them to wear these to their school, they must be 1/2 to 1 inch longer. The length needs to be added only to the bottom not above the crotch area. I haven't fiddled with adjusting the pattern yet. Any ideas on the best and/or simplest way to add this much length? On my 2nd pair, I used 1/4" seam allowance when sewing on the Fabric B trim, and that helped but more length would be better. Thanks for any advice.
