DESCRIPTION
The Sea Glass Tank is another design in my Scrappy Collection. The patterns in this Collection have been specifically designed to use up all those part balls that are in your stash.

This pattern has a very unique construction method that makes it fun to make. it uses two 3/4 grannies joined together along the center front and center back to make the tank. The unworked 4th side of the granny becomes the armhole. A granny strip is added to the center front for a decorative detail and the back closure has the option of being joined with a granny stitch or being laced-up corset style. The tank can be made cropped or extra rows can be added to the bottom to achieve your preferred length as was done for my version of this pattern.

DIFFICULTY LEVEL: Intermediate

SIZE INCLUSIVE
XS - 5XL.

MATERIALS
Yarn: #4 medium weight,
Carron Cotton Cakes - 520 yd/ 8.8 oz - 485 m/250 g (60 % cotton / 40% acrylic)
Although this yarn is listed as #4 in my opinion it is slightly lighter (13 wpi).
Remnants of 2 colours, Beach View and Beachglass were used.
The cake was deconstructed and the colours were placed as per my preference and based on the quantities. Smaller amounts were used at the beginning for the shorter rounds and larger amounts for saved for the end for the larger rounds.
Quantity: Amount varies depending upon size.
Approx 500 yd for XS up to 1,000 yd for the 5XL
Hook: 5mm
Tapestry needle
Measuring Tape
Scissors

TECHNIQUES
Granny square

Here’s some of the things testers said about this pattern:

  • I was very satisfied with the finished item.
  • It is a great top for summer and day trips.
  • I especially liked the granny strip going down the middle.
  • It was really fun to see how a different layout could create a top.
  • I really liked the slit at the back.
  • I liked how it (pattern) tested my current knowledge and also like to learn something new.
  • I like how the pattern, while using simple stitches, looks more
    advanced than it is.
  • I iove how you split the yarn and used the different colours.
