This tutorial came about because it was requested on youtube to teach a finish for stretched fabrics. You can use this technique on intimates and swimwear! Let’s get started!
Supplies you will need to complete this project:
Plain Tank Top
Marking Tool (Fabric Chalk or Water Soluble Marker)
Seam Ripper (for mistakes!)
Step 1: Mark on the tank top (on yourself or on a dress form) where you would like to crop it to.
Step 2: Draw a straight line across the tank top where you marked it, making sure to do it on both sides so that it matches back to front.
Step 3: Measure the width of your elastic and make a marking that measurement away from the original line. Ex: my measurement was 3/8″ so I marked 3/8″ away from the original crop line I made.
Step 4: Draw a straight line parallel to the original line at the marking you just made. Repeat step 3 from this line. Make sure to copy the lines on the back of the garment.
Step 5: You should now have 3 straight lines across your garment, matching at the side seam with front and back. Using fabric scissors, cut at the lowest line one layer at a time.
Step 6: Putting the bottom half of the garment aside for another project (stay tuned for our next video for this one!), ensure that the elastic is the right measurement around. Make sure that the elastic is tight enough for you at the waist and cut the length.
Step 7: Take both ends of the elastic and bring them together. Ensure that the rest of the elastic is not twisted and sew both ends together using your sewing machine or a needle and thread if you’d prefer.
Step 8: Folding at the stitch you just made, mark the exact opposite end of the elastic with a pin (see video for visuals). Fold the elastic the exact opposite way so that the pin you just made and the stitch are in the middle and mark either side of the elastic with a pin or fabric chalk.
Step 9: Fold the crop top in half length wise and mark at the hem on the fold. Unfold it and then fold it in half lengthwise in the opposite direction and mark on the fold at the hem again.
Step 10: Take the elastic where you stitched it closed and pin it to one of the side seams of the crop top on the wrong side (or the inside) of the garment.
Step 11: Take the first marking you made on the elastic (which should be exactly opposite to the stitching) and pin it to the other side seam, making sure not to twist the elastic.
Step 12: Pin each of the side markings on the elastic to the centre front and centre back markings on the crop top at the hem.
Step 13: Sew the elastic to the hem of the crop top with a zig zag stitch, making sure to stretch the elastic so that the fabric on top is not bunched at all. Your fabric will tend to curl so make sure to straighten it out as you sew. Back tack at the end.
Step 14: Fold the hem over the elastic once so as to hide the elastic. Using a wider zigzag stitch, sew all the way around the hem again on the elastic at 1/4″ on your machine. Back tack at the end and you’re done!
