Seam sealing with tape is generally easier, less messy and more effective than liquid sealers. The time and effort involved is not much different than if you were working with wool and pressing seams as you go. I developed this technique about 10 years ago and have appreciated not having to use liquid sealer except in circumstances where taping is awkward.

Remember: S.T.T.S.

OR, on light weight fabrics you may want to S.T.S.

Try this technique: The key to making seam sealing with tape easy is to use a Teflon Pressing Sheet, a cool iron (between synthetic and silk). Always test on sample fabric first! Iron the tape over the trimmed seam with the pressing sheet on top of the tape and the tape placed evenly over the seam. If the seam is not top-stitched, trim seam allowances to 1/4", finger press open and place the tape evenly over the open seam allowances before pressing with the Teflon Pressing Sheet.
