Title: sewing curved hem..help
Post by: bplant on February 10, 2013, 09:18 PM
How do you handle the material when sewing curved hem?  I am trying  to hem a leading edge with a spar pocket.  What do you do?

What type of kite?  Are you folding the edges over or using a separate LE piece? Curved hems are tricky depending on how you are doing it

I have yet to sew on ripstop nylon but its been my experience in sewing curved hems to go real slow to keep everything lined up. like as slow as possible.

yeah....i take it slow with these....if the foldover section is wide enough and actively fighting being put into its place then i would use some double sided tape to hold it in place....

you can also use scotch tape to hold the folded over layer over...just sew right over it and then it is super easy to remove....

I hold the sail material in place with 1 in. wide Scotch blue masking tape.  Use the regular blue masking tape and not the low stick type.  Cut off lengths about 2.5 in. long, and then fold over about 0.25 in. at the end so you can remove the tape.  I line up the cut pieces of tape on the edge of my glass cutting table, which I first clean with rubbing alcohol then wipe dry with a paper towel.

To hold the sail material, space the tape about 6 in. apart on straight sections and closer together on the curved sections.  For leading edges, I tape both the front and back sides at the same location.  Begin sewing, and then remove each piece of tape once are close with the stitching.  For smaller projects, I cut the 1 in. wide blue masking tape into widths of 0.25 to 0.5 inches.

In challenging areas, I just sew through the tape, then lay a steel straight edge along the stitching and carefully rip the tape along the stitching, and remove it from the sail material.

For outside curves, you can cut tiny nicks along the edges. For inside (concave) curves, cut out tiny notches to remove excess fabric. Slow was good advice- slow and don't stretch things out too much. Ease it in as you go. If you have to stop and lift the presser foot, make sure to stop with the  needle in the down position before lifting the foot.

Fun stuff!

I was pretty new to sewing curved hems when I made the NiBan kite, but by the end of it, I'd got the hang of it. It's all double-folded hem.

Gorgeous!

The following picture shows how I use the blue masking tape to hold the hem.  This hem is a single fold for my Rapere Canard kite.  I have used the blue masking tape technique on larger kites, such as my stunt kites, which have a double fold hem with a leach line.

Doug, for what it's worth, you can get rolls of 1/4" masking tape at your local quilt shop. It's sticky enough to do what you are doing, but not too sticky. Save you the work of cutting all those nice'n neat pieces.

madhabitz,

Thank you for the suggestion, but cutting up the tape is therapeutic for me.   :D  I used 0.5 in. wide strips in the picture.
